Wait until you get felguards to talk about easy.

One thing about locks is that shadow bolt is 2.5 seconds and lightning bolt is 1.5 seconds (I think). So per cast the warlocks are going to be hitting a lot harder. Gear wise, shaman don't really start getting elemental stuff until outland.

Warlocks kind of go through the doldrums from 30-45 but after that the talents start to work together and turn everything into easy mode. Then after a respec into multiple felguards it was crazy how easy everything got.
