Saur just uploaded part 2 of the system breakdown: http://www.youtube.com/watch?v=RSAbLRnGiWg
The Wonderful 101 is awesome and all, but Platinum games does a shit job at explaining their own combat mechanics.
I'm approximately at 75% (Normal difficulty, mostly silver/bronze/consolidation) and I had no idea many of those features even existed. They're not in the menu, unlike the Unite-Morphs, which all came with a tutorial.
I'm at work right now, but when I get back home I'm going to practice some of that stuff. I don't want to go into the endgame unprepared
