Hmm, I do enjoy the current battle mechanics overall. Having to pick every action actively makes soloing more fun and immersible I think.

However, when grouping it up, it is nigh impossible to communicate or make jokes mid battle while trying to fight of some foes. So I am for auto-attack feature, if it was something so simple and easy, and could be toggled on/off on the fly.

IE, a toggle button is assigned for active mode, kind of like how now (autorun+camera) adjusts the camera zoom while mid-fight. You go cursor over to light slash or heavy stab, etc, hit the lock button, a little lock icon goes over that move, and you will continue using it as stamina permits, until you hit the lock button again. Maybe even lock multiple abilities. Slap it on Aegis Boon/Speed Surge etc, and those moves will be used automatically once the timers are up/wears off.
-course, than people might get too lazy..

I only skimmed this thread, if this idea was already made, than just consider this as me agreeing with it
