in summary, if a target goes stealth. they enemy should no longer be able to target them.
and when a buff exists it should do its job (padme protection up).
Further more, i have a concern regarding a 3rd situation.
i have seen gba lead bugs in ga/tw completely ignore taunt, after their initial salvo of attacks, said attacks have triggered a teammate to taunt them (zaalbar as example). and the bugs continue to attack any other target they wish, instead of switching over to zaalbar.
Not a pro or anything, but I am a computer guy. I think that the assists are cued before the buffs come into effect, allowing the assists to continue on targets that become stealthed. It could also be that mass attacks are linked to who is targeted, and their state at that time, but I'm not sure. I think that the check from Padme's zeta is only applied at the beginning of a turn, so since all of the assists happen on the turn the protection up is gained, that part of the leadership is not counted. Also, I think Nest acts differently because her protection up is not a 'buff' buff. There is no green box floating above her head, unlike hound's tooth. I think the official excuse for most of these is probably something about loops and spaghetti code.
