I am not questioning your mental stability - THIS would be insulting -, but I ask whether you have given it two thoughts about what you are even suggesting!?
Except for your first 1-2 points about Bane and Miasma which unfortunately are not explained any further - despite it could've been the most interessting part of your post - you jump right into buffs that are on scale we've never seen before, and left without any explanation why you are even bringing them up.
And here is what we saw: except for chain stratagem, they are copy and paste from the job guide - the note about Nocturnal Field on Succor was still there. The buff section heavily lacks proof reading. For ED there is still the Aether cost notice, but you just added it doesn't cost anything... this is unfinished, and confusing to say the least.
And as WaxSw has described in detail, your suggestions don't make any sense without any explanation or wrote down reason.
I can't see any design changes that justify such buffs, so we are back to the point that this section is still not done.
In fact, your changes would make SCH even more boring and monotone than it already is, since Sacred would be mandatory in any situation, and the gauge would be overflowing with no way to spend other than on Fey Union.
Focus on the interessting part, and keep the balance in mind. If you can't come up with numbers without breaking it, either don't fix on them or give a rough direction, so you wouldn't go overboard.
So far, all I can say, those changes are - mildly speaking - not good, and those that could be interessting are not explained, so I can't make any of it.
