...Why not just use the PF if you really wanna progress through things fast or just use the tank yourself on Lv90 dungeons? Even better, if you really want tank to pull more than a group in leveling dungeons, why not communicate it through chat? I'm all up for new tanks to learn how to tank (it's fun y'know, pulling two groups and slapping as a tank), but surprise-pushing a child who can't swim into a pond isn't a really good idea- and tbh, real toxic IMO.

Even a beginner's... whatever it is in english, also is official, says that DPS's role is to attack enemies which is targeting your tank, you aren't exactly supposed to pull an enemy, not just "tank is supposed to take hits".
