The original thread was mysteriously deleted, but Kalgan responds to a thread confirming his statement. In particular, he says, Blizzard is looking at the severely gimped, non-mobile totem dropping mechanic as well as improving some under-used totems (Windwall Totem, anyone?). In an uncommon display of candor, Kalgan also expresses the direction they will be taking with the forthcoming changes, noting that Shamans are "pretty well gimped" in 2v2 Arenas. Enhancement Shamans should also expect an incoming buff as Blizzard is expecting to get at least one spec viable in 2v2 -- and it's, gasp, Enhancement!
Asked if these changes will actually make it into Patch 2.4 or if these will be another tease+heartbreak by Blizzard to the Shaman community, Kalgan unequivocally replies, "Ah no, don't get me wrong. There will be buffs in 2.4, it's just a question of which buffs." So apparently, there is light at the end of the tunnel. I know it's easy to be skeptical about this considering how Shamans have repeatedly been shafted, but Blizzard's surprising openness -- heck, the mere presence of a blue! (and not in a thread-deleting kind of way) -- in the forums is a refreshing change of pace.
