Hey.....You know how Squall has roughly 3 different variations of his Renzokuken? Each variation differs in the number of hits he does before the random finishing move. It's like either 4, 6, or 8 hits, i think.
Anyway, they could do the 4-hit for a level 1 special, the 6-hit for the level two special, and so on.....
Also, I could see how they set his attacks: weak punch for using his fist, medium for a gunblade attack without the trigger, and Strong would be the gunblade swipe with the trigger.....
