West Point, GA
Yeah I could do my best healing if I could find a safe spot and just stay there, but if I had to move my healing capacity tanked. Of course I did JUST start healing in FL and we quit raiding as a guild a couple of weeks into DS so I don't have much experience with it.
As for mouse, I use a Logitech Cordless Optical Trackman. I have two additional buttons that I have set to vent PTT and autorun. I do have buttons on either side of the scroll wheel I could probably set to L/R strafe but I'm not as accustomed to using those buttons because well, I really don't ever use them.
