I think a good start would be for looters to circle BEFORE the first strafe. That gives AA A chance to do its job and makes looters powerful but require making sure counters are not around first. It's not perfect but it's a start
It would also make the ability an utter waste of muni.
Its current implementation might not be perfect, but we really do not need even more forgiving reckless play and blobbing(4 of the loiter abilities for 4 factions are AI or partly AI as well).
