I wouldn't necessarily agree that burst is "needed." Remember the drain-teams of a few seasons back? They functioned off of the concept of just running your opponents oom.

Like where asonimie is going with his locks: dot a lot of people up and start fearing stuff. Who knows if it'll be competitive, but it's a new approach, and you never know what can work until you try it.

Having said all that, I'd have a hard time giving up the shaman. The can just do sooo many different things, and the stacking of totems just pushes it over the top.
