"equalizing potential xp gain, combined with the designing of content that can challenge high-level players, is a better direction. Granted, it would take more work, but the work would have a worthwhile reward, in that there wouldn't be a glass ceiling lingering for people who want to see how far they can really go."

We have different views here. I want higher levels to take some time, not just a week of hard playing to reach Highmortal.

Equalizing potential XP gain is fine, as long as the max possible is a LOT lower than it is.

And that would still require a pwipe. Unless you have no problem with suddenly having everybody reach level 50 in a few weeks or maybe a month. A mud of gods...
