I understand that. While I think that is new, that isn't the problem. What seems to be a problem is that SK will stop pulling saying 'group needs rest' even when not snared (or at least, I don't see a snare in the buff window). When it does this it shows 'current 83%, threshold 90%' even though pull threshold is 90%. Just 30 seconds ago it did it again. I immediately moved the SK around - he was not snared. But he sat right back down with the 'group needs rest' message.
It seems to me that if I get snared the 'wait until med stop threshold' logic kicks in, so all conditions to exit med and start pulling need to be met, rather than just the removal of the snare. This would be OK, except the chars aren't medding (never reached there med thresholds) so it can take a while before starting to pull again.
For myself, I wouldn't mind if 'stop pulling if snared' was an option. While this may be a great addition for pulling back to camp, I often run in HunterTank mode where this option isn't necessary (doing that now). I question the value of the setting in the first place, as usually the snare happens on the way back to camp, and not the way out, so I don't know how often this will really help the puller avoid a death.
