When the good, nice players get too many bad players who "play the way I want" and go out of their way to underperform, they eventually go for the "find someone competent" and run almost everything with them.

It doesn't help with said bad players also asking people who play right to stay out of the df or "get used to it".

What we end up with is a df with a larger pool of bad players who also have a short fuse as they are starting to lose their carries, especially if someone is new and still learning.

The only advice I can give you, OP, is to make some friends/join an fc that will run content with you instead of relying solely on DF. Otherwise, build up tolerance against whiners/haters but definitely always seek to improve yourself so you don't end up as the "bad player".
