Except paladin is being changed to fit 2minute burst meta, so thinking it's going to retain the sustain damage is sheer copium otherwise Paladin would be getting reworked lmao.
So like or hate it, that's the reality of where paladin is most likely going to go, is dump everything into raid buffs, with a big burst and a small burst every other minute.

But I seriously doubt Mikey's wish for Paladin rework will happen to be perfectly honest, since he's assuming the rotation loop will remain the same as it is at present, but it's SE they dumb every job down when they rework, so highly doubt it will come to fruition. And if, just if, Mikey's idea came to fruition, play around with a 2.22 GCD would be awful, which would get worse long term, due to SkS on other gear in past and future BiS, can't rely solely on GCD of one tier to base theories on.
