Drop info of chests/eggs.

[Valsacar]

Does the number of players attacking make the chest/item drop rate better or worse (i.e. would it be better or worse for me to solo the bosses myself?)?

It seems to me that only one player in the group would get the locked. I have never seen two or more players getting it. Hence, in a way, you can say it better to solo the boss.

Not true, I've been in groups where 3/4 got crates off the same boss (same for chests).
