the new trees have me excited. i dont think the bloat is something theyll be removing; GC has stated that bloat isnt necessarily a bad thing, as it forces you to choose which talents to pick up. in essence, its a guard against the whole "feral druid" issue that dominated most of BC. that is to say, One Build to Rule Them All, effective as a tank, a pve dps, and strong in pvp (if not top tier, but close nonetheless).
now we have a reason to use rend on targets in both pvp and pve, and dont need to spec into enrage in fury (unless we want to more or less guarantee its up full time, which is possible).
i can see a build like this 54/14/3 being quite strong in arena pvp, with appropriate point swapping based on composition (i.e. add blood frenzy if heavy physical dps). even fury can get in on it, altho i dont think id do the expected fury build if i went fury pvp. id like to try more of a support/survival fury build, going with a fast 1h sword/mace/axe + shield so i can shield slam for the extra dispel and keep furious attacks up on two or three people at a time with white damage. itll take a lot of target switching, but in the span of a single piercing howl, you can keep people snared long enough to get one stack of FA on two or three targets, with enough rage to refresh howl at the end of it and double that stack on one or two of those targets (assuming said targets are scattering, which they should be).
now, you could probably do a TG dps pvp build too, but for me, having a fast OH would be necessary to keep that FA debuff on, as well as running into the problem of having to stack a lot more +hit. still, it could work pretty well with the right support or a rogue and/or hunter adding their MS debuff effect on as well.
id call my mood cautiously, optimistically excited. things look much better than they did before, and there looks be to a lot more play variety in the fury tree, which is always a good thing. arms still seems to be rather MS-centric, which is a nice way of saying the arms playstyle is stagnant (imo) but what they did with this push has shown they are willing and able to change that. heres hoping arms changes even more (for the better).
