This could be a nice compromise, even though i like the current system much better and i believe after a certain rank most of the people will turn it off, but i can understand that at the first days in game when you don't have a lot of abilities and you still have to learn how the battle system workss it can be frustating.

I don't like only 2 points:
- normal attack don't consum stamina
- auto attack keeps going during battle regimen

This way the auto attack is basically a dot. Making it consume stamina and stopping it during battle regimens will keep the battle system more tactical.
