the title says it all.
we all... most of us heard about the arcade redux, the gunslinger patch and the new upcoming ranked misions that bring a new boss..
so lets see, what do you think?
my gues is something thats connected to the ancient ruins wich old tortodrone guarded. they could also give some hints about the core.
I think that the new boss would be an undead boss who is very old and has a cane with him.
