Unlimited defensive power is stupid.

Same as George, it just ranks up default END slightly. It's not that good of an ability, it just sounds wanked up.

You cannot simply be Nanoha without first donning the appropriate hat.

You can when you've found a way to use a legit magical girl heroic spirit.

A+ Divinity is Gilgamesh level, are you Gilgamesh?

Nope, better. You don't have to be 2/3 divine to get A+ divinity, there's another way, but I'm obviously not telling as it'd probably reveal who that servant is. Hmmmmmm I think I can tell who it is, there's really only one servant like that.

Too many A+'s.

I'd be inclined to agree, if all those skills actually did anything. Divinity looks pretty and that's it, Charisma lets you tell normal humans what to do better(And that's technically a misnomer at that), and Guardian Knight will get their END to be like A when they're defending people, which looks good on paper but it's not a game changer.

I'm guessing this servants capability totally relies on the Noble Phantasm, since Class Rep already knows those skills are essentially just place holder skills that do little.

I see you Class Rep, trying to fool everyone with your clever ruse.
