The removal of physical levels, the changes to claiming and the Link system, have all had a major impact on game play, and I don't think all of the various activities, at various levels, have been balanced yet.

For one, I would prefer that PL not become better than both soloing and partying at levels 1-40. Somewhere around equal would be OK.

Leveling 40-50 solo should not be both easier and faster than Leveling 1-20 solo. Again, somewhere around equal would be OK.

In my opinion, the following changes are called for:

1.) Leves 1-20 need a bit of a boost to Exp reward.
2.) Leves 30-40 need a slight reduction to Exp rewards.
3.) PL on much higher level mobs needs a lower cap on Exp so it is not better than partying with players your own level.
4.) Please examine the Link system so it is more in tune with the actual party strength (possibly a few less links for any given party strength).

These changes do not need to be drastic. I'm proposing minor tweeks to make things less noticably lop-sided.
