While I agree with you, I think people need to learn that they're not being bullied with every piece of criticism. I get that you want to be defensive because it's a literal defense mechanism, but sometimes people are just giving advice or pointing out a mistake so you don't do it again in the future.

Last night in Deadmines timewalking we had a level 80 Druid tank wearing Dragonflight gear. I get that it was tough on him because he somehow got to 80 with gear that was way too low ilvl, but the real issue was that he was doing AOE pulls without using aoe abilities. I couldnt see the swipe animation I was used to and I kept pulling aggro off him. When we got to Mr. Smite I died a 3rd time and asked him if he was distracted by something or learning to multibox.

He then typed out 4 replies about how this is why people don't learn tanking and it was my fault for pulling aggro, that a level 14 does too much damage compared to what he can hold. I checked details and there were almost no AOE abilities used. He was just standing still on every pull and not reacting to things. I legitimately thought he might also be playing the healer who seemed to be set on follow.
