Drop Rates Question

[rrra]

All of them except cow queen are not effected by mf. Cow queen might but, but I am not sure about that one. I'm not sure about the chests either. As for player number, I think its the same as with keys/frags. The drop rate is higher if there are more players in game. That being said it usually isn't worth it to take on the harder bosses with a lot of players in game. With the exception of Cow Queen, if its in a special area that isnt on normal bnet, its generally more efficient to do it on players 1 (if soloing) in my experience. Although I'd be curious if anyone else has any suggestions on the optimal number of toons to have in game when soloing the higher difficulty bosses.
