I can't post a build but the main focus for all blasters is to kill kill and then keep killing.

Yep. Pile up as many bodies as you can; that's the main idea. Ice/Ice/Cold will give you plenty of tools to help avoid adding your body to the pile.
PM me after 6PM EST and I'll forward you my build.
Here's my quick and dirty Ice/Ice/Ice build:
Level 1: Ice Bolt
Level 1: Chilblain
Level 2: Ice Blast
Level 4: Frost Breath
Level 6: Hover
Level 8: Freeze Ray
Level 10: Swift
Level 12: Aim
Level 14: Fly
Level 16: Health
Level 18: Bitter Ice Blast
Level 20: Stamina
Level 22: Ice Patch
Level 24: Build Up
Level 26: Bitter Freeze Ray
Level 28: Ice Storm
Level 30: Shiver
Level 32: Blizzard
Level 35: Freezing Touch
Level 38: Ice Sword
Level 41: Combat Jumping
Level 44: Flash Freeze
Level 47: Hoarfrost
Level 49: Hibernate
Skips frozen fists (because I hate the look), Chilling Embrace (PBAOE and I just don't need it) and Frozen Aura (Melee range AoE minion sleep)...
I also skipped the APP Snow Storm and Frozen Armor (hate the look).
And, really, even skipping those powers I've got WAY too many powers. MOST times I just use Bitter Freeze Ray at extreme range, then Freeze Ray as I close in, and finally I throw Bitter Ice Blast at the unfrozen foe, then Frost breath the lot (usually defeating the unfrozen one). Then I just cycle the single target attacks.
Sometimes I fly up to a foe and "drift" into melee range and use Freezing Touch to put one foe in a block of ice (fast animation and when you 'drift' into range they USUALLY don't attack right away but give you that "what are you doing here?" kind of look as they pause)....
I only picked up Ice Sword later because I didn't need or want anything else, but now I've got it, and slotted it, I'm liking it. I don't blap much with my blasters, but using Freezing Touch to put a foe in a block of ice (set on autofire) and the Ice Sword to hack at foes who are -already- in blocks of ice seems safe enough to me. 
Can someone posts a ice/ice/cold blaster build. i'm not sure on what the focus is for blasters in general and ice/ice blasters.
Thanks
