The standard in raids should be that people are able to perform at a certain level, a level where they are at least able to perform their rotation and know mechanics unless they are new. Mistakes happen, especially if the content is new, that's not the problem. But if I raid and use pf and get a Bard that doesn't use songs even after I politely advise him to do so, then something is going wrong. Right now the standard is, people can play as bad as they want because we don't pay their sub. And I couldn't care less how these people play in dungeons etc. But the moment someone joins a fight with an enrage timer they should at least try their best and not start crying if someone calls them bad, that isn't an insult, its the truth. But I agree that giving advice should be given in a somewhat friendly way.
