In general, I believe it makes a bit more sense with summoner that if the summoner goes down, the youkai cease function at this point. Since this fact is truely part of what makes Summoner frustrating to deal with as a whole, and plus, it's almost like a free pass to not lose the fight when you should. As for other summoned creatures, Shine knights would be the only ones that would also have to have this apply to for fairness. Engineer devices are different in the fact that they're relatively immobile and aren't overbearingly strong. Butterflies, They go down from almost anything. Can't quite think of much else that'd be this kind of issue.
