Right now I have a single macro that'll use w/e ability I'm talented for but it will only display the tooltip for the first ability listed in the macro and only if it's the ability I'm currently using.
So I'm asking if it's possible to have a macro that shows the tooltip for whatever talent you're currently using?
/cast [mod:shift] Light's Hammer; [nomod] Execution Sentence; [mod:ctrl] Holy Prism
Generally though I would stick to one per fight and use my clcprot or clcret to make an aura button to watch it's cooldown and switch the ability off my keybinds. Your best talents bets are atm:
Holy/Prot: Light's Hammer
Ret: Execution Sentence
