Why Speed Pulls?

[Sareal]

But why would you aim low? Why would you take a principled stand against doing more when you and your party are capable of more? If we all do our best, then it's a better experience for everybody.

Because I don't always feel like it. I agree with what you say to some extent, but then, why the toxic behavior over it? Doing our best means speed pulling the entire trash floor even thought the tank did not express wanting to do it? There is probably a difference in opinion on what "doing our best" could be in this case. So basically, since the voice of majority is more "relevant" then I should speed run and if I don't, it means being detrimental to the experience of others? That's kinda one-sided. Like I said, I don't go in a dungeon and force people in slow runs. I do and still speed run when the group is being nice about it. But when they are being ass, it's not better than me going in and being an ass about not wanting to mega speed run.
