ok i'm thinking of doing raids, BG's and maybe an arena team. heres the build i'm thinking of

it smells pvp spec, and theres not much points in fire that increases your damage from fire spells. Pyro is prolly the least used spell in pve (from own experience) and i didn't use it in pvp either. but it all depends on is: are u gonna pvp or pve the most? if pve is what ur gonna go for, change your spec for more damage
