Considering this is a troll thread, I probably shouldn't bother, but I'm gonna do so anyways considering other people have brought out points that make sense already.

If you are actively getting offended because someone is trying to point out a mechanic that you're failing, or if someone is trying to tell you to use your basic 1-2-3 combos and you get angry; you are a bad player. This also applies to the other side of the spectrum, if you get angry that people aren't performing the top 1% of damage for their class in a regular duty, you are toxic and also a bad player.

Literally, just perform decently enough so that people aren't forced to carry you through content and no one will complain. But if you start getting angry that someone is trying to give you advice and help you, then you really shouldn't be playing multiplayer games where it is heavily dependent on team work.

Now if you'll excuse me, I'll go back to enjoying my B-day and see if this thread gets out of control.
