What do you guys think is the cause of severe lack of Tank users?

[Juzjuzz]

Have none of you noticed how they added literal doors to slow players down so that you do not pull the entire instance or are expected too?
....
God forbid if you a new tank because the community who have some that have been here since ARR seem to have extremely unrealistic expectations of tanks.

Salty ppl complaining about bad players + bad players complaining about job they don't know very well. In the end they asked for "make things more easy for me pls", even if they didnt want it. Result : SE made sure aggro is not a problem anymore, and the dps rotations for tanks became easier.
Tbh i don't think bad/new players complain out of nowhere, it's oten the result of "elitist" players or saly ppl telling then to "git gud" all the time lol.
I remember stopping tanking after doing castrum meridianum and the Praetorium (because i felt completely lost and didnt want to get in the way of others later).
