Would Garen's backswing have to be reworked if the punch was readded?

Garen's current backswing is a basic cross slash thingy in alternating directions with a thrust for crits. The old Garen's lack of a backswing allowed more variety in his auto attack rotation because each auto attack would reset to his idle animation. Also, on the topic of advanced animations, will we be seeing injury walk animations at low health in the future? I THINK Sion has an injury walk cycle, but I honestly haven't seen him all that much to be honest.
