Perhaps I'm the one misunderstanding here, but if I read the changes for tremor it seems a direct buff, you can now break fear on yourself when it matters, without wasting the totem...
In addition it got extra fast pulses, so you dont get feared for 10 yards before it even starts working! Yet most shamans out here see it as a nerf, why?
I support this change btw, both for pvp and pve, since tremor was instagibbed anyways by good players in pvp..
