I have a mentor crown, and help people when I have knowledge of what they are asking about, but when I run dungeons and trials, I usually get complete silence from the group.
We wipe several times to them not knowing mechanics, and their job rotations, but they don't even ask for help.
I could tell them how to do the mechanics right, how to do their rotations right, but you often get push-back if you tell people how to play.
Which is why I tend to do the "give advice when asked" thing, but as I mentioned earlier, duties can often just be a complete silence of failure due to it.

Please guys, if you need help, just ask, I'll help as much as I am able to.
