Sorry if you already know, but you can have pally be out of the group and only have the alts heal him, and he will get full exp instead of sharing it. If they help kill, some exp goes away. If they are in the group (even if they don't help), exp get shared. And if you skip to higher level stuff that you normally can't handle, then it goes faster, since the mobs are worth more and the quests are worth more also. I might recommend like +4 +5 mobs. Depends on your group setup.
