I like the current battle system, but it could use some tweaks.

Introduce a haste like spell to conjurers or a passive haste trait to any DoW/M. The stamina bar works very well with the current BR/SC system. If adding auto-attack meant removing normal attacks (eg. spirit dart, light shot, heavy strike, etc.) they would have to revamp the BR system as well since normal attacks play a big part in them.
