I think the problem is the power scaling for the KQ hasn't been taken into proper account. It suppose to get increasingly difficult, but not in the sense where it is an exclusive KQ for the Pay to Win Players.
It needs to be scaled so that the game is playable for FREE TO PLAY players who is your average joe.
You do know after lvl 90, it become pay to win right? its been like that for years now. It wont change as long as players keep buying sc.
