im playing pvp as frost obviously and the spec is more for bgs cuz im not specd into replenishment

anyway id like to have some opinions about my gearchoice and gems etc

here is my armory: http://eu.wowarmory.com/character-sh...%A1&rhtml=true

also is 850 res fine (i feel comfortable with it) but ive seen mages with 1000+ resil and less haste.

also should i go for 2part t10 and drop the 4set pvp bonus?

p.s. inbe4 lol rating and/or lol comp both are just for fun
