The content you mentioned, Coil, is the only thing in this game (well, maybe excluding Titan) that actually requires a team that works well together. This is the content meant for teams who want to work as a team. It's not a single player game, it's supposed to have some team work.

And really, "I'm perfect, it's jus so difficult finding people who are as good as me"? Funny how that line is used in every single thread where people explain how they can't beat anything.
