Power-leveling is absolutely BROKEN

[Frein]

I wonder how it'll be dealt with so that it's still a valid way of levelling in line with the 2-3 month model. Perhaps the xp per mob with someone much higher level will be reduced substantially, or maybe they'll include some system where only one low level can get exp from a power leveller so each person wanting to do it needs a friend to help.

I'm thinking they'll somehow incorporate the highest level player's level into your exp calculations, similar to how FFXI did it. That or they just cap monster exp in some other way that most likely ends up hurting legit parties as well.
