I like this suggestion. I stopped playing when the level difference was so huge between us friends.
So let’s see. A Level 500 char invites a Level 1 friend but they can’t play together unless the Level 500 creates a new one. So he creates a new one, they level up together most of the time (but not every time) so there will come a point that they can’t play together anymore. One ends up with a Level 500 while the other with a Level 450… both hardcore gamers but yeah, they don’t have the same pace so they can’t play together now. Because of the too high level cap, there is only a small window where friends can play together, despite having almost the same pacing.
In short, the game is designed so that casual gamers who wish to play with their friends who are hardcore gamers should turn into hardcore gamers too just so they can level up together. But of course this is not possible, so casual gamers can use the power of $$$ to catch up really quick with the hardcore peeps.
So yeah…I hope a GM or staff would confirm that the gameplay will stick like this. Better let me move on from this game this early before I keep my hopes too high.
