I'd like sole survivor back, but your living dead, TBN, and blood weapon changes aren't wanted from me.

Living Dead can be healed up quite easily if you coordinate with your healer or if they are just competent in general.
Why do you want to outright nerf TBN.
There's a sweet spot with blood weapon to hit all 5 if you do it on melee. Can't do it on spells, but oh well! Try getting some skill speed materias and go for 2.36~2.38 and activate Blood weapon on 75% of the GCD refresh.
