People already have the option of doing things besides xping. Nobody is forced to xp (using xp as a verb here). It sounds like you're in favor of forcing people to not xp, via the agency of the limiting buffer. At this time, i'm not in favor of limiting options.

In regard to the main point above, i'm hearing that, in short, you don't want people to be able to level as fast as they are able to right now. I don't see high levels as a problem... levels are more-or-less relative anyway, but *if* that opinion is shared by administration, there seems to be a simple solution to slow down levelling while making minimal changes within the game: simply double or triple the base xp required to level. Existing characters get a same-race, same-guild reincarn, and wind up at a lower level. That is... if high levels are really seen as a problem. I don't see them as a problem beyond lack of challenging content, as i said before.
