I think it's cumbersome to add 3 levels of raid. Especially if they keep the convention that you have to complete normal Coil to unlock Savage. It was annoying enough having to do Garuda, Garuda Hard, then Garuda Extreme. Having to do 3~5 bosses three times over? That's pretty irritating. If story mode Coil isn't required to continue on with the main story, nor required to enter normal Coil then I'd be okay with it.
