should I just grin and bear it ???
If you are being boosted, you DON'T want to be in a party with your friend as I seem to remember this affects your XP gain. Be seperate and make sure you are the one who starts the attacks on mobs.
You won't get good xp in the Deadmines at level 10. The deadmines is recommended level 14 min I think... something like that... so long ago since I was in the deadmines =\
Yeah you tag, they kill if you're in the same party you get less xp. Mages friends are even better, you just tag a lot of mobs and then they kill them all with arcane explosion.
