I haven’t looked at the changes yet, but some classes could benefit from a pruning IMO. I don’t play Unholy DK because there’s too many cooldowns and separate single target vs aoe buttons.
For specializations I do currently play, I have macros to put cooldowns(& some base abilities) into a castsequence so everything fits neatly onto my hotbars and for ease of use.
It’s really a mess with my Holy Priest using Oracle talents. I just macro’d Premonition to several of my regular casts so I don’t even have to worry about it.
