Garfonso,
Thanks for the great guide. I have some Shaman abilities in my build. 96 lvls worth and I use every masterable Shaman ability I can, especially Expulse and the DoTs. Expulse works great on undead.
I especially like your trick on pulling with Rust spell. I wonder if a Battlemage can use it Or more importantly, do I have an extra hotkey for it if I can :/
