I'm definitely not sure how this keeps popping up despite the answer being clear as day, but okay.

The reason why I've quit tanking in the first place was because of DPS pulling for me. You're literally making someone work harder just for you to speedrun and be done with a roulette. You don't pay my sub. Yet, you get to decide how other people play the game. I'll pass. I'll dps. I don't regret making the switch either. Every now and then I run into a group who wipes because the tank and healer didn't have it together with the large pulls. I just use my potions and whatever defenses I have in order to avoid wiping with them. They can do the walk of shame. I'm not joining.

Bottom line. Everyone needs to stop throwing expectations on every single person about a personal playstyle and just play your role. This isn't League of Legends. You never know when you'll run into a tank that only does single target damage.
This whole "You pull, you tank" mentality needs to be buried as well. That type of retaliation makes you look like the bigger dummy.
