Rather disappointed, I was, to read that the new Aspect of the Beast, the one that buffs melee AP, was removed in the last WotLK beta release. Oh well. Guess I won't have to worry about mana after all, since that leaves me stuck with Viper.
Edit: ...or not, since Viper procs off ranged attacks. Thanks, Wren. Lrn2read, Gweryc. But according to an anonymous reader, contrary to what I read on WotLK Wiki, Beast is still in the game and still has the melee buff. Hopefully it'll stay that way.
