Season 2 certainly has me playing the game more, no doubt. That bump in visuals is really, really nice, and the two new characters are awesome additions. If their levels are any indication, I'm excited to see what we'll get for Cinder and Riptor (hopefully the bloody spike poles will make an appearance).
Unfortunately, the more I play, the more stunned I am by the mess of a UI. Yes, it's far, far more slick than the original, but it's just a maze to try to figure out where anything is. You can see what you've unlocked, but you can't see what has yet to be unlocked in the same area? Instead you back out three times back to the main menu, go into the store, and then go into your desired field?
Of course, there's the huge step back in customization that's already been mentioned several time. A message to any developers taking over a project: NEVER REMOVE FEATURES. EVER. You can rearrange stuff, you can implement new paths to the same goals (like the new XP design) but, no matter how trivial you might think they are, do NOT remove features.
So..yeah, I'm liking everything that takes place in a match. But so many things that were changed just for the sake of change have resulted in a big step back.
