I've been reading the warrior forums for a while now and it seems that tempest is in 99% of people's builds, and they seem to be in a part of every warrior pvp build that has been posted. Is Tempest absolutely necessary for warriors in pvp? I can see the obvious benefits of just having it on without even putting many points into it or any at all, but is it absolutely a must have? Are there no other viable substitutes for tempest?
I'm leveling a warrior and i am a free-to-play scrub right now but i want to at least get a character to max level and mess around with endgame content before i decide to put any cash into this game. Am i going to have to shovel out money to unlock the tempest soul or am i better off just rerolling now?
In short, does Tempest make or break the warrior in PvP?
