Let me explain my problem this way:
My Shaman(my main) casts Flame Shock(instant cast) and my Warlocks cast Immolate(3sec cast) all on the same keypress (Numpad 2)
So I press key Numpad 2 then try to approximate 3sec before I move to my next spell.
What I'd like is to stop approximating those 3sec and see it countdown that time above the target frame (which I do watch)
I wouldnt need a slew of numbers just 1 simple rectangle with a timer in it so I know my alts are done casting.
I'm not sure how castsequencing would fix my timing issue but I'm open to ideas.
