I've been playing since Heavensward and I have been told to shut up when trying to help players in my mentor roulettes. Most recently in the newest dungeon I tried to offer a tip on the second boss and got told "you're not a god just because you do savage". But I feel it's important to point out that I can probably count the number of times I've gotten this treatment on one hand. The bulk of players either 1.don't respond or 2.are friendly and thank me for the tips. I don't think it's a huge wide spread problem, I think we're just more likely to remember if someone responded in a rude way so it seems like a bigger problem than it is. If someone's running into hostility a lot after giving advice they might want to re-evaluate how they're giving that advice.

As for the "read tooltips" suggestion to teach people how to play, I don't think I've ever read a tooltip in this game haha I cleared 2 ultimates and 6 savage tiers without ever reading one. But I read guides on jobs I want to play because a tooltip just doesn't give me the exact information I want. A guide gives me more context so I absorb the info better and have a better idea of when to use what. But obviously a whole in game guide isn't feasible. I would rather they just update Hall of the Novice and make it mandatory for new players. People absorb info better by actually doing stuff so a more in depth Hall of the Novice would be nice.
