Punishment for exploitation of Power Leveling

[Travesty]

I believe the thing is the high level is partied with the low level, so the low level does not have to claim anything. the high level just blows them up and the low level is on auto-follow or something.

That's the way it is now, because the exp limiter for a high level in your party isn't working. Once that's fixed, the high level will have to be outside the party and the low level will have to tag the mobs first in order to get exp.
