There's a problem but I don't see it the same way.
I think the big problem is that there is no way to "catch up" new players with established players. MMOs would periodically raise level caps and release new content which sort of functions as a soft reset. Obviously this isn't an MMO, and catching up can be argued to only matter on one's own shard, but I still think that over time it should become easier (faster) for the the average player to gear up a robust roster to say g8 or g9
