Been my experiance the little sobs won't stop trying to separate even if it means going up walls or strafing me for 10 minutes straight. If its 2-5 they try to line up side by side, more than that they tend more and more to re-overlap and then re-adjust over and over. Bad luck?

I doubt something like this would have a short enough recast for abuse.
Sure you can pull a mob away from someone for a second, but its just gonna go after then again.
Did you miss the part about lowering the other persons hate? Pretty useless to move mob without that yeah, since the other person would still have all of their hate and it would run right back.

I kind of wish I hadn't used the language "like draw in". It kind of implies depop-repop at this position and I think a kind of reverse knockback is a better mechanic and was how I imagined it. And it was all about the hate steal not crowd control and draw was usually nailing the whole group. So I really opened a can of worms huh.
