I have an HP voodoo mouse with five buttons. Have some healbot stuff tied to buttons 4/5. Hadn't thought about scroll up/down, but I'm SO USED to that being my camera zoom I don't know if I could train off of it. Good idea though as ripping the scroll wheel would be pretty easy.

I'm still curious to hear how others are handling encounters where there's a need for coordinated movement and healing. Specifically when having to deal with team movement and heavy incoming damage, how do you keep your DPS spam going?
