## About The Pull Request
As potato requested after the merge of #78744 these should have separate
concerns even if they are very similar.
In addition I improved how mob chains react to glide size changes, and
swapped PAIs to using these signals instead of an override of
`onBruteLoss` just because I can.
I tested it but the unit tests will catch me if i did it wrong
