There's a mentor in NN on my server who routinely gives out the worst advice. I was in a dungeon with them helping a sprout who wanted to learn sage better and they wouldn't even mention using things like zoe, krasis, soteria or physis II as tools. They were telling the sprout to keep E.Diaging the tank during the packs. In other discussions on jobs when sprouts asked, they said PLD was the worst tank and proceeded to describe taking off it's signature kit abilities from their bar and describing them as "useless."

This person plays the 1-2-3 wombo combo of any job, doesn't read their tool tips and refuses to use more than half the abilities available that makes those jobs shine, then passes on those habits.
