I confess: I've moved with the W-A-S-D keys as long as I've been gaming, and although I keybind quite a few abilities and use Grid+Clique for healing, I have been a clicker. In an attempt to rid us of that shameful habit, K- sprang for Belkin N52TE's for the two of us for Valentine's Day. I set mine up last night. I don't have much to report yet (other than a warning that apparently one cannot bind a Power Word: Shield mouseover macro to one's mouse. /lame.
Full report tonight at 11. (or when we finish Naxx 25. or when I write one.) Stay tuned.
