As a healer i can say some parts are totally true like:
DPS love to run upfront and pulls mobs. I end up burst healing them because they cant stand more then 3 hits and i get the aggro while the tank tries to taunt and get the aggro back.
In Zergs we have the problem that tanks keep taunting doenst matter if another tank has the aggro of the boss. So it turns around and hits the meele group hard. Or even better: “Off Tanks” (an Axt with aggro gem - doesnt make you a tank ffs) believe they can hold against a real boss and blame us healers that he dies within 2 hits.
In my opinion, everyone should atleast talk once with a tank how it works and how taunts and aggro work in new world. Not the same as in wow for example.
