You could probably say everything you want just as effectively without being a bass, just so you're aware.
I like these suggestions quite a bit. People, maybe only a few, maybe several thousand, have been clamoring for pets to be utilized in a fashion where the SMN will switch them around constantly as a fight changes. Utilizing each pet and not just parking it right on Garuda for 95% of most content would be an amazing way to actually feel like a SMN if you're swapping around your pets to get different benefits for your party. When the expansion hits and we get our guaranteed Ramuh egi, and the to be confirmed Leviathan Egi, if they gave them statuses like what you said, I'd like that quite a bit.
If we did that, made Contagion an actual SMN cooldown instead of having it be tied to Garuda, and then I saw someone else's suggestion that Fester crits could give an additional Aetherflow stack. That allows you even more possible uses and possible gained stacks if you're lucky, and if needed, you can probably use an Energy Drain for the additionals if the RNG is working with you. I know people have said that Energy Drain is a DPS loss through and through if you're not using Fester, but no one should honestly care if you're still Fester'ing just as much if not even more depending on how often you are crit'ing and getting those bonus Aetherflows. This way, since Fester is tied to SMN and Energy Drain is on ACN, there would not need to be an adjusting to Energy Drain to help SMN with it's MP issues and mess up the perfect flow that SCH has right now.
