That /stopcasting sounds good in theory, but in practice it's been a big problem for me.

You trigger a global cooldown when you cast a spell.

So if you cast lightning bolt or chain heal, it triggers the GCD.

So then if you have the GCD and cast your /stopcasting it doesn't cast it.

So you end up having like 1/2 your guys or none of your guys cast a heal when you most need it - and if you spam the key, it'll stop casting the heal!!!
