lol - and that was a stupid thing for BW to do in the first place. isn't it universally agreed that the buff to focus was uncalled for? now name one other AC that has 3 excellent pvp specs. your exception proves the rule.
Focus was still viable before the buff, the buff just made it moron-proof. The spec is almost as easy as pyro PT now.
All I'm saying is, if one class can have 3 viable trees, then either BW needs to nerf the one class or buff all the others, as it's not fair otherwise. I could argue that VG/PT and Guardian/Jugg have 3 viable trees as well, but not to the level of marauders/sents.
