Duration of Shared Grp XP Penalties

[Kassel]

The dev letter clearly states the class-based penalties that were designed into the game from the start with the original vision of what hybrid classes were meant to offer in terms of power created unexpected results because that "greater power" or "extra group benefit from the class" never materialized in reality. I really can't spell it out any better than what I just did... I'm sorry. I'm going to drop it before I enrage a dev... but I don't see how this cannot be called a bug.
