If someone isn't doing an AoE rotation, that sounds like a great time to offer some advice. Because if they are new or returning, they might not know how to do it.
Which kinda brings us back around to "offering unsolicited advice is rude/toxic" that's also been said in this thread. When someone is doing something obviously wrong, the two most likely explanations for why are that they don't know any better or that they don't care. One of those has a chance of being corrected with some polite advice, which, if accepted, will help that player in everything they do going forward. That sounds like a thing we should be encouraging people attempt first, before resorting to the kick button, right?
Yet, so many people trying to offer advice get slammed by the community for it.
