I disagree a lot with a lot of this, as a Bless User. There are definite chapters were using Bless is probably a better idea than ignoring the "problem", or just trying to get an enemy down as fast as possible on a giant, spreading surface. Plus bless's resistance/immunity to decay and other statuses/dodge bonuses gets way too overlooked.
The only change I would make to bless is to not have it cost memory, but not for balance, merely that story-wise it makes sense to have it readily available IMO.
Buffing up the dodge bonus makes it far stronger than what people give it credit for. I think it gives a good amount of both, and works alongside leadership extremely well.
