I actually use every monk ability, except Touch of Death because long time dont play PVP. Maybe transcendence because it requires 2 buttons while it could just be a warlock portal. Maybe CJL for non-healer specs...
On the other hand, I think many of the warlocks abilities are bloaty. Ex:
* Dark Regeneration, normally macro'd with healthstone
* Twilight Ward, normally used in conjunction with other defensive
* Curses are currently almost a bloat, because nowadays you'd rarely use enfeeblement with its nerfs. I'd prefer making it more powerful (even with a cd) than removing it though.
* The whole lv 60 talent tier is bullshat (burning rush, blood fear, etc). Mobility has to be toned down, CC has to be toned down.
* Grimoire of service requires a lot of extra keybinds, which is bad
* New mannoroth's fury is bloat
* Drain life is currently almost a bloat, but I'd say it should be made meaningful
* Soul swap should be removed from the game
* Rain of fire and SoC are superposing AOE mechanics and on the past we also had hasvest life
I don't consider Enslave demon a bloat because it's an iconic warlock spell which normally doesnt require a key binding.
