Hopefully something they can look into adjusting again when Season 3 launches. I am not saying we should have everyone to level 50 in a month, that wouldn't feel very satisfying at all. Expecting us to spend years to get characters to 50 is just on a whole other level.
I also think there should be a way to get more of an XP spread, if I am playing ranked (which I usually do most of the time) I am not always using every character. I am obviously going to more times than not use the characters already at level 50 because my rank is on the line. I shouldn't have to go into something grindy like cpu matches and survival to grind out other character levels, it isn't fun at all. At least create a way to make it fun to reach the higher levels, nobody wants to grind in a fighting game.
With color 9 and some accessories locked behind levels instead of KI Gold it's obvious they weren't just trying to pinch cash out of people. There hearts were definitely in the right place, just needs some adjustment.
