Ok so with my priest+locks I have an issue.

I have a lot of "interrupt what I'm doing to cast something" but on a staggered list.

Ie: death coil. Each warlock has a macro something like:

/stopcasting
/castsequence reset=120 Death Coil,,,

And so on.

I have a similar macro for fear, howl of terror, etc.

The problem is, all 4 warlocks stop casting when I use it (obviously) but I can't seem to find a way to synchronize the stopcasting with the castsequence so it only stops casting on the warlock who has Death Coil ready. Is there any way to do this?

If I remove the stopcasting and just spam the button so that as soon as the current cast is done it casts death coil I have 2 problems. 1) Almost 100% of the time more than 1 warlock casts the spell. 2) in a real emergency I dont have 1-2s to wait to cast the spell.

Any way to make this a bit more friendly and usable?
