yes, try to get 42% faster hit recovery
work on getting a wizards spike with 7%fhr and +all resis/+single resist/+life replenish/+% dmg to mana/life/stat
and take out 1 cold skill/12 fhr and get one with life.
you want 120% faster hit recovery at all times
he 8fps breakpoint IS 105% but you usually doublecast ( will get you killed) if you don't have atleast 120% fcr
since you play in east, you are allowed dr%+block%<95%
in pvpeast and most tournaments
that way you can take out the ravens ( put sojs in both places)
belt, get a crafter caster belt with
10%fcr/+life/+mana/+resist/+fhr/+str
maras? try getting a bonewing or crafted fcr/+2skill/stat/life/resist amulet
dueling zons you probably DON'T want max block %, because you will get stuck blocking losing mana from energy shield and be rendered useless
and in TeamVTeam you want to be able to hit and run, your sorc isn't meant to be a tank if a barb is next to you
edit : your skills are VERY nice, what level are you?
put more into cold mastery and having 1 mana requirement for teleport or less is very nice incase you get mana burned..
