Got this problem with uneven cooldowns in my rotation, ruining it :/
9sec/6sec cd rotation with 1 8sec spell.
this 8sec spell sometimes causes me to run 2 spells too close to each other, causing 2 cd's to finish at the same time.

what i'm looking for is a addon, that might look kinda like the bars in "guitar hero" next button to push, coming down a line, hiting a cross line/box when you are supposed to hit the button.
would make close, and/or uneven rotation much easier to hit
