basicly what the subject says can i change the setup from moving with mouse.? to moving with keyboard.
IMHO, the game is much easier to play with just the mouse. There is no point in 'strafing' either, (The only real reason to want WASD) as moving around doesn't make archers or nukers miss or you any harder to target.
Personally, I can't think why anyone would think WASD is good for these games...unless they come from WoW. Diablo I/II were both PnC, as well as Darkstone through Dungeon Siege and others. (Sacred, Divine Divinity, etc.)
