The new meter system feels really natural to me since I've been playing 2D fighters so much lately. Pyrrha's EX moves are all really straight forward since she only has one that can be used to extend a combo.
I'll just have to get used to playing Soul correctly, instead of casually, which is the way I've been playing for years, I mean, when you can rape all of your friends by just spamming 66BB and then blocking every once in awhile, and you play like that for 5+ years, it's a little awkward to break the habit.
