First, we are dynamically creating "experience," the advancement mechanism
in EverQuest, to offset an additional "experience requirement" attached to
certain character classes. Secondly, we are creating additional experience
to further reward those who adventure in groups. Finally, we are increasing
the experience rewards in some areas of the world.

The overall effect is that some players, depending on style, should be able
to advance their characters up to nearly twice as fast as they once could.

This was taken from EQ vault. ^^^

Thats sounds out of whack to me, so here are my Max increase calculations:

Group of all hybrids (DOn't laugh I was in one last week in karnors, I(bard)
was the primary healer...)

Old xp = 1000
+10% (for old group bonus) = 1100
Each player gets 183 xp

New system (in a dungeon which got a 20% xp bump)

Total xp = 1200
+20% (new group bonus) = 1440
Each player gets 336 xp (1440/6*1.4)

Not quite doubles (which would have been 366 xp), but not far off. Of
course this is a truly bizarre circumstance where a group of hybrids would
be fighting togteher in newly bumped zone with no deaths...
