I think ur build is very nice to do many dps. I link an alternative build, the most important thing of this build is counterspell (if it's not bugged in this server). You can change the frost build like u think better:
Thank you both for replying.I'm glad that someone reads these texts.Shadren posted alternative build which i believe to be excelently balanced for PvP and PvE due to certain talents in arcane tree.However it is not as quite powerfull as the previous build for dmg dealing due to the absence of ice floes,permafrost which are duration and mana eficiency effects;the abscence of frost chaneling and elemental precision further reduces mana eficiency.The abscence of ice floes is very bad for frost mages due to the fact that it is basicaly a pure survival talent because of dramatical reduction of cooldown of spells like ice block,cone of cold (when you hit enemy with it it has his speed reduced by 50% which is quite an asset when fighting melee classes) and so on.Counterspell on the other hand is very powerfull and sillences enemies (not 100% but silences) even without talents.Arcane fortitude is very powerfull talent and the Shadren's build is excelent for leveling so i would warmly recomend it for that purpose but not exactly for PvP.I hope i will soon have time to write more about mages and hope that other people will read them as well.Once more i thank you both for replying and posting
