There is no incentive to tank.
The expectation is that the tank does research out of the game on the ‘correct’ routes and that they have a plan and encyclopedic knowlege of all mechanics, after all Dragonflight has been out for THREE WEEKS, so it’s basically ancient at this point.
If anything goes wrong, it is the tank’s fault.
If you go too slow, it’s the tank’s fault.
If you go too fast, it’s the tank’s fault.
If you pull too many, it’s the tank’s fault.
If you pull too few, it’s the tank’s fault.
If that hunter backpedals out of an AOE and pulls the next group over, well that’s definitely the tank’s fault.
And what, dear reader, does the tank get in return?
Why, nothing. Nothing at all.
Save derision, of course, because you are simultaneously doing too much and too little DPS as a tank.
So why would one pug tank in WoW for the already toxic AF M+ community?
I really don’t know.
