hmm maybe during a grapple u could aim low for weak moves such as a "fireman's carry" and then aim up to do "suplex", and depending on the direction that u are pressing on the joystick it would determine what move u did in the weak or strong category.
Hope that makes sense.
oh and of course being on the recipient of a submission would have to shake both controllers, and the submissioner could pull back on the controllers simulating pulling back someone's leg in a sharpshooter. Going even further, if u sway ur controller left to right u could shake ur opponent such as in a sleeper hold or Kurt Angle's Ankle lock, of course all should be done 1:1, no pre done animations.
Okay and lastly but not least I'd like to see the pointing function used for things such as aiming where to throw people. This could be used for throwing an oppenent into your tag team member or throwing a character through a particular spot up top of a hell in a cell match.
what do u guys think? These are only my first initial thoughts, I probably could think of some better stuff after awhile of thought.
