What's the point of tapping the Q and A keys if you only attack with it. If you could charge attacks or if tapping them exactly when they charge gave bonus damage, I would understand. But the way it is now, I can literally just mash the keys and not pay attention. On top o that, it seems to be an endless grindquest. The exp distribution makes no sense. It looks like you get more xp for finishing off enemies, but that concept doesn't go well with high dps-low dps pairings because you have to wait to allow the other person to attack, and thus extend the grinding process. You then potentially take damage which forces you to return to the checkpoints to heal, which also wastes more time.
