Hey, I dunno if there is any real solution, but I agree with you.
I'm an aspiring tank who hates being pressured by DPS or healers to do speed runs.
Fortunately, I haven't seen any of that since it's the new expansion now but I really don't have fun speeding through things. Even if I have already done it twenty times or more.
I play games to relax, not feel more stressed out.
