There's no reason to not use the Avoid AOE feature in some modes, and failure to kick it on manually would result in loves of people death looping on certain FATEs. Like it or not, you guys have to be protected from yourselves occasionally. You could modify the behavior by modifying a single line of code in ffxiv.lua if it's really THAT much of a bother to you to automatically use artificial intelligence to avoid having your face exploded.

I've said this before, but I'll repeat it here again:
None of the settings are saved per mode, some settings are automatically kicked on or off depending on if they would interfere with the mode currently in use, and it happens as soon as you change the mode.
