If you're intent on keeping the powers in the same place i see a couple of problems:
You only have smite and shadowmaul as attacks up to level 30, i did this on my dm/regen and it got seriously tiresome when your enhances are shot and shadow maul misses a lot, without hasten in there earlier you will spend a lot of time sitting around waiting for powers to cycle - add any baddies with slow will really show up your attack cycle.
When building this in hero planner I found that with the lay of the epics i ran out of useful places to put slots at 48.
If i were to make some power choice changes i'd say bring air super in much earlier, bring hasten in much earlier and see if you can stretch to energy torrent in the epics.
With hasten and a recharge in air super coupled with shadowmaul means you can supe them to the floor and still afford to miss a shadowmaul as supers recharged just as maul finishes ready to keep them flipping.
I found on my dm rgn that in full flow i can still be left gasping for endurance so found conserve power very much a requirement on top of 6 slotted dark consumption and 3 slot stamina and quick recovery.
anyhoo, if nothing changed power wise heres how i'd slot that build (air super would have 2 recharge in it but this version of coh builder doesnt allow that):

I can honestly say I have never had end trouble on my lvl34 DM/Regen (3-slotted QR and single-slot in Stamina) unless fighting end draining mobs... but, I suppose it's more likely if you're running FA... *shrug*
Based on my own experience I would suggest the following:
1) Slot Reconstruction and Dull Pain with Rech first, then heals (say 2 rech, then 2 heals, another rech and last heal) as you'll want it up as often as possible. In the past I felt fine with 2 rech but, on my freespec build threw a 'spare' rech in and haven't looked back since 
2) Acc, Acc, Acc... well, maybe 2 would be plenty until you can use FA but, even then, I'd suggest one in each attack.
3) Unless you're having serious end trouble, I'd suggest swapping Dark Consumption with Hasten and Air Sup with Stamina.
4) If end really is a problem, put some endred in your attacks, can make all the difference.
All those points are from my own experience and are all my opinion. In the end, go with what works for you and have fun!
yep, i agree. i often think that the '50' spec requests and such like are answered incorrectly by posting end specs, and i just did the same 
i've found that attempting to play a 50 spec on the way to 50 is often very painful, certainly the enhances on the way are rewritten at 50 when the build is really optimised.
endurance use, yer on the way up to 50 his endurance was pretty good, but the 50 respec pushs the character right to the edge of the endurance envelope.

looks pretty funky to me
@ExtraGonk
neither air superiority or Touch of Fear are needed to solo anything in the game, and in a team you will presumably be there for damage...so controlling mobs isn't needed
in fact the power you need in order to solo EBs/GMs that are impervious to AS and ToF is MoG
ToF can be great in PvP 
Main reason I've got it...
Air sup= infinite knockdown= hah, try healing NOW you smarmy bugger! (directed at /regens). Also known as hah, try flying NOW you little goit! (directed at hoverblasters).
It's a better choice than, say, Shadow punch.
Touch of fear= just uber. I've gone entire fights by using this to act as though I'm in elude. Carry a few lucks with you (or, if you're like me, 15 at all times, except 20 for PVP) and you won't get hurt much. Or, if the luck favours you, at all.
Right, so enough of that, I knocked up a build using those powers.

Disclaimer: I'm not experienced with /regen. I slotted where I saw most bonus. Example, the third recharge in reconstruction is worth 2 seconds. YMMV, but I hardly think 2 seconds make a difference of life and death. UNLESS you're rooted in shadow maul. One recharge in revive, because I think it sucks. You don't want to be dead, and with resilience I really think you could get by with wakeys, maybe taking shadow punch or siphon life to fill out your attack chain.
If you're going purely PVE, then whip the slots out of ToF, or drop it for another attack. It's nice, but without any backup it can't stop a boss. That's a PVP slotting of it, mostly designed to hold a squishy long enough to... well, squish.
Didn't 6 slot fly, you have SS for speed and 2 slotted stamina covers the one slot I moved from fly, and is more usable elsewhere. In fact that slot means stamina completely covers SS, integration and FA, leaving base end + QR to keep your blue bar full.
Slotted Dark Consumption like I did because if you need end often, then I have failed you. Or you're fighting an /elec. Either way, 2 minions and you're at a full bar of end (from 0). It'll be accurate enough too.
Only put 2 accs in your key powers (buffs, SM, and MG) when you have FA.
Your attacks should cycle well enough, but as I said I would consider dropping ToF if it's PVE, or Revive if it's PVP. And yes, I know that shadow punch is quicker, cheaper, and faster recharging than siphon life, but it's always nice to keep that green bar high enough that Reconstruction gathers dust.
Hope that helps.
To Clexeus , swap touch fear with hasten .
Hasten is necessary in regen to get your reconstruction and dull pain up as fast as possible , especially at lower levels where you rather slot for damage .
So best is 12 hasten .
20 touch of fear ,
22 swift
24 health
30 stamina .
Quickrecovery gives beter endurance recovery then stamina , so untill midnight grasp you shouldn´t have any endurance issues , especially with dark consumption .
Regen slotting is fine, except you will be missing that extra recharge in Reconstruction while you are hanging on waiting for it to recharge.
Fly need 3 fly speeds in it, and with QR and Stamina it doesn't need any EndRdx.

I'm not entirely sure where you got that from, but it's not right:
SS end cost: 0.25 end/sec
Integration end cost: 0.24 end/sec
FA end cost (when slotted): 0.3 end/tick (this is an example of hero planner laziness, FA ticks twice per second so in fact has double the end cost planners say).
That's a total of 1.09 end/sec. 2 slotted stamina only gives you 0.69 end/sec, so you're still 0.4 end/sec down.

Huh, that explains a lot. What I meant was that according to the planner, end drain from all 3 is pretty much covered by double-slotted stamina. Also, the planner lists it as .73, meaning a drain of about .05 a sec, or so I thought.
Either way, take one slot from fly and put it in Reconstruction as a recharge, and 3 slot fly for speed.
Also, I'd go with the above advice of swapping hasten and ToF. Awesome though it is, fear is pretty weak until SOs, and the lowest I use it is 30 (sirens)
Was good for Meastro and Dr Vahz........... um then yeah not really needed till the 30s again
"Well, they found my diary today.
They were appropriately appalled
at the discovery of the eight victims
They're now putting it all together.
Women wrapped in silk

I was the opposite, ToF i dont have a use for post 30, it only got used pre 30 and in pvp.
@ExtraGonk
just one thing..get shadow punch..no matter what..shadow punch/smite/(air sup)/shadow maul is an extremly fast chain..
Isn't Smite/AirSup/Shadow Maul good nuff?
i'd say yep, smite/maul/air complement each other and the timing on them works well, you can tweak your enhances so they charge in time for each other easily too. When you're up to 32 and take midnight grasp and then again up in the epics you may find (as i did) that the timing is a bit off, but by then you'll be well versed with how your char runs anyway

damn right, out of all my characters, ExtraGonk is still my most fun pick up and play character if i want to stomp some baddies
@ExtraGonk
My Dark/Regen Toon is now Level 14 so was looking at what other Pool Powers to take.
I was thinking that fighting for Toughness would be good, since if you take less Smash/lethal damage then there is less to actually heal. Anyone have thought on this?
My ma/regen scrapper has Tough.. get it. 
My DM/Regen has tough and I would recommend it but probably not until after you get SOs. I think it was the late 30s before I was able to squeeze it in.
i did toy with a few builds trying to get tough to fit but eventually couldnt justify the requirements (the builds i have at the mo already sacrifice 2 powers i didnt want to drop, let alone have 2 spare for tough), its only smash lethal that it helps with, and in the high game its not normally the smash lethal baddies that kill you.
a lot of people swear by tough on a regen though, i went for the 'things are dead before i need tough' school of thought.
@ExtraGonk
Basically a friend has advised me towards it but the slottings the pig of a battle cos there are so many things to balance in DM/Regen:
