For the majority of the time you WILL be the one that pulls.
It's not extremely common to see DPS pull unless you are unnaturally slow at your pulls. THen you may see it more often.

If you're taking what's considered to be an acceptable pace, then you'd only see it if a player needs to keep their stacks, and they'd likely do it because they're rather skilled and know how to handle it, or accidentally and they derp around and run in a panic. Again, you won't see it very often. Accidents happen and higher skilled players are few and far between in roulettes.
