PvE = Ice/Fire, good combination of slows and DoT means you'll be mowing down mobs at a very fast pace.
High-end PvP zones = Ice/NRG, don't really need to explain, ultimate spike damage.
Low-end PvP zones = Ice/Dev, the classic telebombing build, but it also shines highly as a slowing and "debuff" build.
Blaptroller = Ice/Elec, surpasses everything else in terms of hold mez on blasters, with Elec, Fire or Munitions Mastery you're looking at a total of four holds, plus minimal end drain, plus slows, plus good damage. Something different.
Total gimp = Ice/Ice, it also works as a blaptroller, but Elec having more damage renders it pointless. However, Shiver is a very nice power.
But if you're really set on /Ice... I'd rather go Fire/Ice for PvE, Ice Patch then Fire Ball can be quite nice I guess.
Good luck with it FF. 
I'd have to disagree...
My Ice/Energy used to be able to hold anything (when he had just the two holds from Ice) much faster than any other combination of Blaster, including an Ice/Elec I tested it with. With a slotting of 2 hold/2 acc/2 rech you can almost chain the two.
Ice/Elec was briefly the FotM for zones such as Siren's Call, due to Thunderstrike(?) being available pre 30.. However, many PvP Blasters have gotten rid of their long animationed hard hitters in the attempt for a more fluid and ranged burst damage technique.
Ice Primary in PvE has always seemed relatively weak to me, lacking in exceptionally good AoEs. In a high damage team, you will find yourself doing little against anything than bosses and upwards, leading me to think you might be best off with Ice/Fire.
I really don't enjoy my Ice/Energy in PvE in all honesty.. maybe you should wait a while and do Ice/Mental?
I see theres no love for /Ice. Still, I might give it a go. I won't go /mental cuz in a few weeks there will be sheeeetloads of'em all around and I hate being that common.

[/ QUOTE ]Considering how slow BFR is, that's just wrong. An Ice/Elec fire can fire off two holds before BFR has even finished activating, and a third not long after. And that's without even taking BFR, although you could stack it on top of the three others if you want overkill.
BFR is fairly dire. My Ice/Fire/Elec uses FR and my epic hold instead to give much quicker control

Hey there
I have an Ice/Ice blaster at lvl 23, and its great, so far have:
Primary:
Ice Bolt
Ice Blast
Frost Breath
Aim
Freeze Ray
Bitter Ice Blast
Secondary:
Chilblain
Ice Patch
Pool Powers:
Hurdle
Health
Stamina
Hasten
Super Speed
What can I say, it rocks in PvE, not tried it in PvP (not that kinda guy). The holds, slows and Ice Patch, just keeps the mob at a distance for you to work through them. Ok it does lack AoE damage at the moment, but I have plans for Ice Storm and Blizzard to make life easier.
Teaming, it works well due to the slows in the powers, let the cold embrace you and become an Ice King/Queen.
For the other secondarys I havent had much experience, so cant really comment.

Ran Herostats for mine, with my proc in Ice Storm on a large team it out damages my other AoEs......... on a small team it under performs. For PvE shouldn't underestimate it

After over 24 months of CoX I'm giving Blasters a go. First with Arch/Fire (good fun and rare combo) and now Ice blast. I'm trying to figure which secondary to go with: /Ice (slow cap sounds good), /Nrg or /Elec. I'm leaning towards /Ice for thematic purposes but I don't see myself picking many powers from it (only chillbain, BU, Ice Patch and Shiver). /Nrg should be better if I ever want to do some PvP and /Elec gives a mix of control and extra damage.
What says you?
