On my ice/ice, I'm gonna pick up combat jumping for a -KB proc, assault for the damage bonus, and pick back up hasten after I dropped it to fit in 4 powers from the ice epic. Since I don't bother to spend the $$$ to get super recharge builds, concealment isn't especially attractive to me.
If I didn't already have a travel power and everything from my prim/sec except for the AoE immob, the sleep, and chilling embrace, I'd be taking those. I don't usually skip good prim/sec powers, but sometimes I didn't have any choice, and I did find myself sacrificing travel powers fairly often, so on a lot of my characters those are the sort of things I'm picking up.

This is what it means to be a tank!
I think that's what I like the most about inherent Fitness. It's not just awesome because we can have Stamina at low levels. It's great because it opens up choices we simply didn't have before or just flat out removes some of the hard build decisions we had to make in the past.
Three? I get four! Swift, hurdle, health and stamina! (♥ Drain psyche: never had to touch fitness.)
...On my fire/fire I'll pick up smoke, then take the melee/smoke/ST immobilize earlier.
One my Plant/earth? No idea. Perhaps the fighting pool, just for kicks. (sorry, that pun was free, and unintended.)
My Fire/Ice will pick up powerboost faster, then the ST immobilize/smoke as well.
My Elec/elec never needed fitness, and my Mind/energy was too young.
I'm going Concealment so I can squeeze in another couple of LotG's. I'm addicted to +Recharge on my Mind/Fire. I'm probably going to go for the Recharge Incarnate slot too! Between Consume and Domination my blue bar will be OK.
When I respec I'm also going to drop Mace Mastery for the Ice Epic pool. Sleet and Ice Storm are too good to pass up. My biggest regret is exchanging Scorpion Shield (which is incredibly good looking) for Frozen Armor (which looks horrid).
Freedom: Blazing Larb, Fiery Fulcrum, Sardan Reborn, Arctic-Frenzy, Wasabi Sam, Mr Smashtastic.
I already have Concealment and 5 LotGs, but I went with //Psi to hold two of them. With the extra power choices, I will grab the Fighting pool and respec into //Cold. That will give me the two spots for LotG, and will net me a lot more damage. Technically I could have grabbed Invisibility, but I prefer to grab powers I might actually use.
My post respec build has about 35% S/L defense, but tbh I'm just looking at it as gravy. I've never needed defense before now. Perhaps it will come in handy on the new task forces.
I also considered taking the Medicine pool. Aid Other and Aid Self on a high recharge build (I run about +200%) and Power Boost are both effective with minimal slotting. However, with //Cold I will have more proactive mitigation in defense and Hoarfrost. After giving it some thought, I don't see myself using Aid Other much as now when someone's health drops I just let loose all my ready to go AoE mezzes.

I play heroes on Champion.
I play villains on Virtue.
(Stealth, Invisibility, Grant Invisibility) + 7.5% = 22.5% extra recharge
I'll take it. 
Make a man a fire and keep him warm for the day, SET a man on fire and keep him warm for the rest of his life.

My Super Permadom 3 has invis now, but I couldn't take tp ally as it didn't fit the build. So now it will have it, as to the other 2, I don't know yet. I'm still evaluating if I want to ditch the patron pool and lose the scorpion shield and take ancillary powers.
Of course on the other hand, the build ain't broke so it doesn't need that kind of fixing. I'll like take tp ally and some of the leadership pool.
For Alpha Slot.....I really don't need any more recharge as my SP3 has more then enough to maintain dom without hasten, so likely more defense, maybe an endurance nudge or I'll look at damage resist or more accuracy. So many choices......
Well, Mind Control has a skill that is incredibly powerful in certain situations and just requires one slot to be effective (two to be ideal): Telekinesis.
My Mind/Fire will be taking Telekinesis, Rise of the Phoenix, and either Super Speed or Stealth. I have been relying on ninja Run up until now, and SS would be nice, as would being able to socket a Winter's Gift resistance to slow (which is a pretty crucial resistance for a perma dom).
So with Fitness becoming inherent, what do you think you will replace it with on your Doms that have it? For myself, I'm leaning toward the Concealment pool. I like the idea of stealthing missions, and those powers can take LoTG +Recharges. Also the stealth powers have the advantage of working well with just the base slot.
I'm also happy at the thought of being able to take things like travel powers earlier without feeling like I'm sacrificing something.
So what are your plans? Leadership? Stealth? Medicine, perhaps? Or maybe picking up powers you skipped before from the Primary and Secondary?
