This is how you do it if you want to run slow speed runs.

If your confident in your healers ability to not heal prematurely and dps to wait until everything gets to you to start up then you should NEVER need a new stoneskin or heal mid pull. If you utilize sprint, you might take 1 melee hit per pack, instead of 3 mobs from pack 1 hitting every 2.5s plus 3 mobs from pack 2 hitting every 2.5s, and oh look theres some mobs from pack 3 hitting you as well.

To the OP, get a healer you trust and attempt to do it this way just los pulling using sprint and you will never go back to the stupidly slow way you do it now, unless your in a df pug and you don't trust the healer.
