Due redrawn, i would skip as many melee powers as possible.
I got a 41 AR/Ice atm, yet my main computer bitty dead atm so i try from what i know.
Burst, Slug, beanbag, snipe, flametrower, ignite, fullauto
chillbain, chilling embrace, ice sword, BU, ice patch, ST hold
CJ/SJ/Acro
SS
Aid other/self
Ignite has a very fast recharge with hasten, i added 1 recharge, 3 dmg, 1 range (helps). Shivers imho only wasts time where you can do damage.
Basicly, corner ice patch, CE, snipe and draw a few.
Once on patch, BU, ignite, Flametrower, ignite, Full auto. Ignite can kill yellow (some orange) minions with just 1 spray and BU. Some mobs see a change to get of the ice patch, i use CE to keep em slowed and it gives nice -damage.
Single targets, even bosses i mostly use chillbain (2acc,1rech,2imm) and spam ignite/beanbag. Beanbag can stack enough to stun a boss, add a snipe and its done 
(beanbag/chilbain/ignite on LT, add a snipe and he wont even hit you).
I went for the Munition epic, 2nd hold yet ranged, ok resist to SL but my favo, LRM missile, basicly a AoE snipe.

Took the Force epic myself - Corner Ice Patch, pull group, PFF, wait for them to be around you and falling down, un-PFF while on CE, move back, shiver and finish them. Works wonders.
I have 3x slow slotted Shiver - very wide area soft control that's more powerful than you first realize. Ice Patch doesn't need 3 Recharge, more than one on the same time can sometimes result in KB instead of KD, which is harmful for your ignite doom.

Thanks for comments given me something to think about.
So far I've found that Chilblain, Frozen Fists, Chilblain, Ice Sword is pretty good quick ST damage havent even got build up yet so expecting that to be pretty good at boss killing. I have 2 lvl 50 blappers as well so I'm not quick to drop melee moves 
I as thinking that with ice patch, shiver and snow storm I would have similar control so an ice/storm troller but maybe they die too quick to make control much of an issue? I did think about Munitions mastery it was a choice between those two I thought I would have enough AoE damage . . but I can see how useful PFF would be . . So unsure now hehe 
Is chilling embrace a must have? I thought ice patch did some slow or -recharge but just found out it doesnt

Icepatch does slow, mobs that can resist alot KD will just move very slowly.
CE is just a nice softcontrol, low on health with a mob following, get it in the aura for a second and he's slowed for a few seconds.
Main reason for munitions is 2nd hold. If you face group of 3 mobs (solo), first epic hold, 2nd beanbag, 3rd melee hold. Icepatch, ignite, or just jump back BU and Full Auto. But this can be done with Elec or Fire set too (depends on your attack chain and the redraw).
(Chillbain -> ranged hold -> melee hold -> melee powers -> finish with gun).
I rely alot on slug/burst, main reason why i didnt took shivers. The final power of /ice, the mini-aoe sleep i tried once, but i couldnt find any good situatie to use it properly (outside when u need to heal yourself),it remains sad enough the worst power i've seen on blasters (due its redicules tiny range). Sleep grenade is ranged aoe, wich makes it abit more usefull. LRM followed by Snipe is awsome, since LRM does a knockback you have enough time to start snipe.
In teams, often you dont need more then snipe, flametrower and full auto, specialy with a /kin this set is up every group. Great use is when tanker miss a mob, with the /ice set you can quite control mobs easily.

Made a new blaster to get lowbie salvage, I'm thinking Ice patch + shiver + bu + ignire + flamethrower + full auto would be sweet
This is my proposed build which I will respec into at about lvl 27 (13 atm took burst to fill attack chain) so any comments would be appreciated
