I think combat would be better with a auto-stack mechanic. It wouldn't hurt anything so far as I can see but would greatly aid in players being able to not have to look as much at the cards, just to be able to stack them. Also would be some ideas to for stacking (see also other of my posts) on combat mechanics and card 'points'. - sound fx played as stack level increases (on some abilities only) - visual enhancement in the area around the build up card etc... So many things to do with cards I think it would be good idea to redesign card/glyphs and such so everything makes more sense including the multi-spec stances we'll have regarding different fighting schools and magic schools and stealth/tanks etc.
