Did you know not performing as you think another player should in a group

And what happens if that player is just learning the class and isn't very familiar with their single target rotations, let alone their aoe?

The deciding factor is the level of the player. Are we in Tam-Tara NM or Kugane Castle? Because the previous people and I were talking about bad players in Expert Roulette. If they aren't familiar with their class by 70 then they should look stuff up.

If you're talking about a player in a low level duty then of course it's ok as they are still new and (hopefully) open to learning. And when I'm in that type of low level duty I'll try my best to give advice if I see that they could use it.
