XP is useful to a point, but it is imperfect in pretty fundamental ways (i.e. it would be very difficult, if not impossible, to fix it). That's why I am against any change that would lure monks into paying any more attention to it than we already do. If anything, I would vote for fewer levels:

• Suspect (XP < 200)
• Candidate (200 <= XP < 700)
• Novice (700 <= XP < 2000)
• Monasterian (2000 == XP)

Upon hitting XP == 2000, I'd freeze the XP and forget about it; plus I'd add a second statistic: Average Post Rep. The two stats serve entirely different purposes. XP measures one's ability to function as a trustworthy monk, while the avg. post rep measures the Monastery's opinion of one's contributions.

This is still very imperfect, but I think it's a small improvement.

But, realistically, I expect the system to remain unchanged. It works pretty well, IMO.
