I think what most people are saying is that you should at least try to help. If you do that and they ignore your advice anyway, then you at least have more grounds to complain about it. :P I have given advice before and been ignored but that didn't discourage me from still doing it. For every person that ignores you, there's usually one that does listen. They might not even acknowledge what you said, but you can see it in how they play. I got story Haukke Manor in low level duty roulette and one of the DPS was an arcanist who I could tell didn't have their pet on obey because it went into the first boss room and almost started the fight without the rest of us. So I told them, put pet on obey to prevent that. The arcanist didn't say anything, but their pet also didn't aggro bosses after that so I assume they did listen.
