I have found that when fighters are in a big furball it becomes impossible to reach in and turn the damage dial. We have been picking them up and turning the dial, then putting them back as close as possible to the original postion.
It can be difficult to mark their original position 100% accurately, so we figured eyeballing it was sufficient as long as they are still engaged with all the same targets as before.
I see how dishonest players coulod try to gain a small advantage doing this. So my question is, Is there an official procedure to this process, or some other easy method to do it?
