Is the 0-Click Ban also extended to the first coil of bahamut?

Unintended? Do you read minds? They said they wouldn't change it, not that they never intended for people to beat it that way.

Does the ADS work the same way whether you're currently still struggling with minor bosses or only if you've already engaged him?

If ADS works the same way everywhere you are, no exploit was made.
If ADS only works that way when you've already engaged him, I still don't see any problem.

They are very capable at making one-shot enrages. Perhaps they didn't intend people to deal with it that way, but there was literally no "underhanded exploit" made, so they couldn't really change it without raising some questions.
