"You pull, you tank" is a bad mentality

[Supersnow845]

Let me just clarify here that actual YPYT happens rarely, but petty punishment can happen. If the DPS is a prick, why shoould only the tank be punished for being petty?
Why is the DPS right for just deliberately disrupting the game for the rest of the team?

Etiquette is good behavior, a norm among players. Just because you cannot understand it doesn't make it obsolete.

That’s my point. You are starting off a flawed base. You are beginning with the assumption that anyone besides the tank pulling is automatically disobeying some sense of “etiquette” despite having no functional reason why that exists. Tanks haven’t had necessity of being pullers in so long the vast majority of players playing this game never experienced the game when it was like that. If you want to justify being petty on the game equivalent of meaningless tradition then sure I guess but it’s not exactly a powerful argument. About as meaningful as JP losing their minds when A tank pulls in an alliance raid

So in a world where anyone can pull with no downsides (and in the case of effective use of things like arms length or toxicon can actually generate advantage) the so called “etiquette” is just outdated tendencies to do things the same way for no real benefit which then leads to the question of why are you being petty against a DPS who from a gameplay perspective isn’t doing anything wrong. I’m not even saying a DPS is in the “right” for pulling, I’m saying letting someone die for something that doesn’t lead to downsides unless you let it puts you in the wrong.
