I have to disagree with merging Requiescat and Confiteor. oGCD into a GCD action is clunky af. We already have Bunshin in Phantom Kamaitachi on ninja, and it feels awful in the opener, so rather pass tbh. Might sound good on paper for the idea, but execution will be awful, especially since you often Fight or Flight into Requiscat, you will clip a GCD with this merge.
If I recall, they did mention there would be more reworked on Paladin in 7.0, but honestly they can drop Shield Bash and Cover at the very least, none of the other tanks have access to them, so skills aren't exactly in the necessity category as far as actions go, they are super niche use skills anyways.
