Auto-attack is a step backward.

[Bled]

Simple solution: auto-attack toggle. If you want to play like the old way, you can (especially in the case of arc), if you want to use auto attack (which really is more useful to melee) you can. Don't see how that would add anything detrimental to the game at all.

You can not just simply put a toggle on auto attack and manual attack, too many variables change for that to be a viable solution.
