So you want new content, without making our current gear useless? Without the "gotta catch'em all" the only thing left for this game is a few runs in pve and how ever much time you want to put into pvp.
In order for them to add new content, new items/ cap increases must be put in also. Otherwise those of us that were lv30 before CE dropped would have already been at cap and again have nothing to really play for. You can make the play for fun argument sure, but progression/purpose+ fun is always better than just fun alone(imo).
