As a warlock I end up dotting up several targets with two dots (or even more) each. The time it takes to dot them all up is of course very closely related to the limitations set by the global cooldown. When rapidly changing targets through MT boxes or the healthbars in-game, I don't necessarily always have time to see from the actionbar if the global cooldown has worn off yet. Casting a dot while 0.x secs are left of the global cooldown and maybe even switching my target, reduces my dps potential.
This is why a small addon just showing global cooldown based on instants would be premium. I have searched for some time, but to my amazement not really any good alternatives are even available.
Some ideas (any one of these would suit me fine):
1. A simple square: red means GCD is in effect and green GCD over.
2. Some kind of "pizza"-type circle: Fills up, or empties with a solid color, in slices or smoothly.
3. Just a small bar that displays time and runs down.
Essential: Allow the display (whatever form or shape) to be moved wherever, so possible integration into oCB etc. wouldn't work to my purposes.
I decided to tackle this for my first foray into Ace2, mainly since I play a Warlock sometimes and know what its like when your most meaningful cooldown is the global cooldown. Anyway, here's the result so far. Something like DeuceCommander to configure is highly recommended.
Anyway, I haven't got the whole SVN thing going yet so it's just the zip for now.
As far as I know everything should be working, but I expect the bar will become inaccurate if you're school-locked due to a silence or interrupt in such a way that some magic schools are on cooldown and others are not. The bar only monitors one spell per class under the hood, so if that spell's school is silenced the bar will appear indicating a cooldown, even if other spells in other schools are castable.
Very nice, exactly what I've been looking for. Thanks!
Seemed to work pretty nice even if I got a strange ghost bar after playing around with the 1min testbar and casting a dot. (the bar displayed 59:59 and counting down, disappeared soon though). But since it's not an essential function after configuring it isn't really harmful.
Hard to say what could still be improved, maybe add an option for the bar turning green (or any other color for that matter) and still displaying itself after GCD is over? Might make it a bit easier to react to the bar flashing/switching color.
