The general player base needs to improve

[Stanelis]

Matched parties in duty finder are "my team". We're grouped up with the same endgoal with the same enemies.
You haven't answered the question either: if I'm not allowed to have expectations of their skill, why should they expect me to carry them?

But what is telling you they expect you to carry them in the first place ? If you don't like the group you're matched with, the door is open.
