I've done speed runs, and I do take it slow. I usually base what I'll do based off whatever the tank wants. If I'm ever in a party with a baby tank a high lvl dungeon I've never felt disinclined to bark at them to pull more. Speed running can get out of hand though.. Specifically in regards to low lvl dungeons. Doing a sanic the hedgehog run in say totorak is just ridiculous to me. So in short it's not bad when done right, but a lot of people like to assume no one is new or not used to things being so fast paced these people are the ones who give speed running a name.

Now if we're talking about speed runs in everyday life including the bed room activities then...
