Hehe, okay
What I do for keybinds on different characters in WoW: put similar abilities on the same keybinding.
example
Pally Bubble is on the same button as Deterrance, Ice Block, ... "oh shit button"
Charge on the same one like Blink, Monk's Roll, ... "movement button"
main button mash ability is on 1 - rotation priority goes 1-5 in generell
Execute is on the same button like Hammer of Wrath, Shadow Word: Death, ...
Shield Barrier, Power Word:Shield, Sacred Shield, Ice Barrier, ... "Absorb/Shield button"
and so on...
As you can see you can make your life easy, if you are being lazy in a clever way.
