Right-click to move camera, and tank controls as default for WASD. It sorta fits a more adventure-esque exploration game, but not one that's probably focused on combat.
Ah yes, if you go with an auto attack + skills with cooldowns, MMORPG-esque battle system, then this is fine. But if you want something more action oriented, then you should try a more action-focused setup, like Dragon's Dogma, or a top-down, hack'n'slash Diablo-like scheme.
Yeah I am gonna go with the attack plus skills with cooldown route, but I'll keep an eye on movement through the life of the development. There will also be plenty of movement skills to facilitate movement.
