When does hybrid xp penalty get removed?

[Sadre Spinegnawer]

Yeah. The grp thing.

How many times does the actual mechanics of grp exp penalties need to be explained before people realize, the penalty works out the same way as if you were playing with a higher level grp member, so if one is truly concerned about maxing exp rate, you should not only ask what class, but also what level.

In a sense it is good people don't understand how the group penalties work. If they did, more people would be trying to make that perfect group where everyone else in the group is -2 level than they are, and are all halflings. Or some other such perfect personal max exp setup.
