I wanted to help out in tartarus as I need the gear. I joined team in kiosk and as soon as we ported in one guy yells "cronus" and so we had no choice but to only do him instead of the dungeon. Can you specify hidden bosses on main dungeons so people know what they are getting into when they click team up?
I agree. I've been harping on this subject since last autumn.
You need to be able to tell other players what your dungeon goal is. On top of that, you need to be able to see people's levels. Additionally, it would be nice if you could also see what someone's dungeon role is, if they prefer to hit, support, tank, etc.
If you don't have these things visible from the start, you just add reasons why people should flee their team.
