Elemental shaman do NOT do well in PVE. The lack of shaman attention is not because the class is doing pretty well. I get that not every class has all specs balanced fairly well, but when it comes to shaman, they have the largest disparity across specs. Historically, one shaman spec or another has always been at the bottom of the totem pole.
People make good posts about much needed shaman improvements, and they go ignored. So people get frustrated and start raging on the forums... then Blizzard gives some attention, but usually in the form of "locking thread because it is not constructive." After years of enhancement SUCKING, they finally fixed that MoP, but then made elemental suck bawls.
Whatever happened to "bring the player, not the class?"

Yes to chain lightning removal, but don't forget that every time Blizzard gives a little something to Shaman, other classes usually get two-fold at the same time. It doesn't change the fact that one shaman spec is always at the bottom. Restoration has probably been the most consistent spec across all expansions.
