It feels so weird trying to make this argument since all the tanks have different kits when it comes to protecting/healing other players. I am not a fan of homogenizing all of the tank abilities to be the same, even moreso when you consider PLD and GNB have methods of healing other players outside of using their defensive CD, so they can get the full benefit of the buff on themselves while at the same time healing other players. DRK is the oddball because of their lack of healing other party members, but I suppose the benefit is they get an offensive oGCD for using it properly and have a shorter CD on it, not to say I agree or disagree with TBNs design in the current iteration of tank CDs.
