First, While it is true that Level 20 players are on the same tier with level 80 players, the fact is that if Level 20 players were on a diff. tier, FTP players with high level but Low Arena Power would suffer. I m Level 85 and my AP is 21K. Think about that: If you really want a fair game, base rankings on AP instead. That will allow low level Whales and high Level FTP to truly be on the same level
Secondly, Yes you have to wait 3 moths to get the Krooper Kombo, but the truth is: This is the sort of game that requires long time investment for it to be enjoyable
Thirdly, If every other day a rare character event appeared, then you ll just start maxing out the Characters really easy. Thats not the point. The Fun of RNG in packs, as well as the accomplishment of getting that character after a month long fun is what I truly Find enjoyable
