What do you mean 3 times more drops? so far it seems like the only thing that changes is the monster HP, not drop rate or the amount XP gained.Quote from Pwnstarr
I definetly see advantages in playing up to four people in various runs. You'll have three times more drops in the game, and if people play together they can drop the loot for the specific class and split the loot. In that way you'll have way higher chance of getting items much faster then you would if you'd play alone.
And it's much more fun bashing monsters with your freinds too!
Everyone gets their drops so 1 monster drops 4 times the amount of loot. This however is only possible if you are playing with your friends and are sharing the drops. I guess thats how it works?
Edit: Ofc a random monster could drop loot for person A but not for person B, but if we assume that rares and bosses always drops something more or less usefull than the above would apply I guess.
