Bots, or at least silver sellers, have been running dungeons for some time now. I’ve seen ones at lv.50 dungeon, coming in, out, then new ones arriving to do the same.
I’ve been told there are ones too running 130, so there’s possibility that all other dungeons plausible for silver farming are infested as well.
We might be misled by the positive increase of players in the charts, but there’s chance it’s just some players and silver sellers discovering new ways to exploit the changes that were supposed to help new players and making lots of alt accounts instead.
So much for instance space for the actual players, with IMC whittling down on server capacity for whatever reason and then this issue.
