I came up with this elementalist build - http://www.wowhead.com/?talent=oZVxGzf0cRZVAG0ofxo0s
I see it giving me utility and protection of the Ice tree (Icy veins, Ice Barrier, Shatter combos, cold snap) with damage potential of fire (opener pyro, faster fire blasts, blast wave, higher crit rating).
I came up with this build for world PvP and BGs (my wife and I are going thru with BGs first untill we can get our hands on full S1 set =)) so it is not my planned arena build.
I know couple things could be different but that is exactly why I am here. I would like to discuss potential effectiveness of this build, possible rotations and improvements that can be made.
