As a melee attacker, I don't see what adding auto attack would do for me, and I rarely use the basic attack anymore, using light attack and pummel to branch out into other attacks. Taking those attacks away without somehow boosting the basic attack would be problematic. It would be a nerf to all melee.

I find the attack animations halting in mid go to be more an issue to fix. Its good to be quick in game, but the movement isn't, fluid. One moment I'm in the air for my seismic shock, then I pop up and my pummel hits. I think the dramatic light darkening spotlight moment needs to be cut out in order to keep the speed of the fight going. Or have it for the killing special attack on a mob(make it a "super combo KO" kind of thing.)
