Yes, if there was supposed to be level caps for each League that should have been introduced much earlier on and rewards for players should have been upgraded and tweaked accordingly to allow for steady level progression, as with any other RPG style game if you level up your player you eventually fight and find monsters and other events that grant higher experience payloads in order to level up properly. This move is just smacking of elitist mentality and telling us all that we should be paying you more money to achieve higher levels when that was not the case in the past.
The fact that you are tearing the Tower apart piece by piece leaves me and many other players who have been forcibly dropped down the league ladder extremely irritated and definitely wondering just what kind of message you are trying to express here.
