Talking from some minor experience with both of those sets (having a Mind/Psi at 22 and a Fire/Ice at 25) I can tell you that Mind/Ice is considered to be something that PvP-serious Doms (lol) go at. Now to tell something I believe it's good at:
[*] PvP, to some extent, at least more than most other builds
[*] Single target killing, bosses go down very fast due to
the nature of these two sets
[*] Two different damage types, this helps defeating some mobs with resistance to Cold, for example, but are vulnerable to Psi (CoT spectrals)
[*] As Mind doesn't have any secondary effects in it's holds (except for the minor ToHit debuff in Terrify) Ice can deliver some soft control in the form of slows into the game
However, Ice is a great endhog, and I recommend slotting at least one endreducer to all of your attacks (you can count out Ice Bolt if you prefer that)
Also, having no pet at 32 (which many see as an advantage because they can't "mess things up") means that you must control all, or at least most of them if you're solo. Pets are such great damage sponges that you will notice when you really need one, plus, they clear up the cardboard boxes in mayhems like nobody's business. 
Although the set has no pets, you can Confuse them to be your pets, heh, speaking of confusing one Gunslinger and watch him destroy his group in a matter of seconds 
Also, Greater Ice Sword looks cool (it's slash animation is pretty much like Follow Up in the Scrappers' Claws set, imagine a big Ice Sword in the hand)
I'm sure others have something to add, like Power Boost being the king, etc. 
I don't know any Mind/Ice, I think it perhaps is a matter of concept.
Power Boost is fun. You will be amazed how many different things you can boost with it.
You will probably want to go with Sirocco for patron so you can get Power Sink (great end recovery, and combine with Power Boost to make sappers grean with envy).
I really should do something about this signature.
lol, I like the idea of pay the sappers with the same coin...
Talkin about the pets, i have tasted singularity and the imps, and I have to say that I was so excited those 32 lvls before to get them that when i have grabbed them i have felt a bit sad about them, they havnt solved my main issues, so this is why i have finally thought to go for the mind set.
About the dmg, im totally agree, i feel they can complement each other, so im happy with it.
Well, tnx for ur feedbacks, still hoping more ppl want to add somethin else.
Peace.
I have a Mind/Ice around level 26, it's fantastic. The end problems actually aren't as bad as I thought they'd be (and I say this despite not having any end reducers slotted in my attacks), and with Domination building as quickly as it does now, you're getting regular bars of end back from firing it off. Still, Scirocco would be a good choice of patron, as Power Boosted Power Sink is very nice - I know a /Ice Dom in my SG uses it. I've yet to see how my endurance handles the two larger attacks, too.
The sets can be good in both PvE and PvP, although I think you'd need to make some build changes. I currently have a PvE build on mine, which I might well keep until I hit level 50 - I've not taken Aid Self, which would be the major change. I also have Mass Hypnosis, which I would drop in a PvP build - I've found it to be very useful AoE control, especially with Domination and/or Power Boost. It works for me because I mainly duo with another Mind/Ice, though, so there aren't AoEs waking everything up.
Out of the two secondaries that have power boost, Ice is propably better than energy. I havent tried ice myself but you dont need much for it to be better than energy. At least ice has secondary effects. My mind/en is lvl 33.
Hiya, guys, some news about my project of dominator pvper, the unknwon 'The Reminder' ...
Yesterday night 1 brute asked for a duel in arena, and I was so close from the Arena Palace, that i said yes... Well, i kno actually im lvl12, he was lvl13, he still dont have access to his mez protections, but I defeated him 3 times, and then he left... So, 1 win for the dominator, isnt it??
He was SS/ela, wich gives me a bit of proud... Anyways, i felt that was so easy i could still be beatin him... I was hit just once or twice, and with a KO blow, which makes me eat a BF.
Well, now im lvl13, and lookin for lvl30 and test this out in Sirens...
Meanwhile, peace for all. Best regards.
PS:dont look at the sig, i need to update it.

AFAIK Electric armour gets status prot. at lvl 10... So he could have had it. Quite n00bish to fight any domi without it
Still happy for you and good you are enjoying domi's so much. It's great playing
I got a mind/ice domi at lvl 30 atm, and i will tell what i've noticed with him:
-Squishy killer, power boosted hold will make them held long enough to finish them off with ur blasts
-Telekinesis is a great power that can be used as a panic button when ur getting more then 1 to take care off
-Terrify is ftw, in PvP its great to fear players that trying to get you (you will noticed how evry1 will go first for you)
-If a squishy pops a BF, leviate is damn useful, with hasten u can send them up in the air a hell lot of times
But it's not easy to handle a domi in pvp. Most blasters and scrappers will do evrything to kill you as your so squishy and cant take dmg. But anyway, hope you will find your mind/ice as fun as i did
Hiya,
After playing some toons, Im really surprised with these sets, mainly because:
* IMO, mind is considered the best primary set, because it has a bunch of control tools. Ice could be the best secondary set, with a sustained dps (it is usually compared with fire), has powerboost, no snipe, and a really cool debuff included in all his powers.
* There isnt no guides about a mind/ice dominator in no where around. I cant understand why, becoz im playing 1 and im enjoying the time, and being safety all the time.
So, any opinion on these sets?? Any special info?? Im not talking to give a build (neither pve or pvp), i just want to take your feedback about these sets.
Tnx a lot.
Peace.
