The xp differential is certainly an issue, but it's one that can be corrected, with some effort.

It's an issue that has been lingering for 7+ years, and even consciously and deliberately preserved by admin (I spoke with Madoc about it personally as an issue, and he said that's how he wanted it) and suddenly it's such a big deal that people want to use it as a lever to wipe everyone's progress?

The only 'solution' that's been posed as part of the upcoming changes is a static xp cap, and i think it's an exceptionally poor idea. Limiting people is not the way to go... 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.

As things stand, people in the middle level ranges are still subject to the same differentials (not a lot of correction has been made to equalize guilds from an xp-potential standpoint).
