So after going through a couple arcade lines, I decided to jump into an online match. I figured I'd get smashed by 3 Kratos players like with the beta, and surprisingly, not a single one. I forget who 2 of the players were, but me (a LV. 20-something Ratchet) and a LV 180 Ratchet. I thought I was pretty much done for from the start because he mastered the character by now, but I ended up going something like 12:2 and dominated the match.
This is proof that just because you play alot, it doesn't necessarily make you good.
