Power-leveling is absolutely BROKEN

[Sorel]

Now if you guys was saying Yoshi-p can you get rid of the bug where if an LVL 50 player grabs 20 mobs then is invited to an lower lvl party and exp is not reduced then yes i have no problem with that you guys just want pling gone just to be gone, and making false statements about small stuff that happens w/o pling

I believe the highlighted would be an effective solution (I also believe DarkStarPoet is the advocate of such a solution). Light Party and Full Party should be the most effective source of XP in the game. Once that becomes true again, grind-parties will be prevalent again.
