I swear that I'm not trolling when I ask this, but is there something wrong with the keyboard that makes it unusable for Naga owners? Cramming all of these abilities onto the mouse via the 12 button side panel and middle mouse click sounds great, but that seems like a lot of extra work for the hand that is already controlling click precision (be it clicking to move, clicking targets in D3, selecting targets in WoW while tanking, aiming in an FPS or whatever else).
I'm looking for legitimate input because this is something I wonder about. Personally, I can't stand to have more than 2 buttons on the side of my mouse, and the LMB and RMB mapped to abilities or movement. I don't even like to use MMB's scroll-wheel click.
I can see to an extent how it's useful in a game like WoW where people for some reason never bother to change the default keybinds from WASD for movement, and so their hand is ridiculously crammed on the left side of the keyboard, but for a game like Diablo it seems like putting everything on the Naga is solving a non-existent problem unless you actually only had one hand.
