some1 know that fcr is working on casting frozen orb ? thats mean if more fcr than soso faster casting frozen orb ?

Well. There is a delay. But casting it a little bit faster means the cooldown will start faster and you can more quickly move and teleport again. So it boosts damage a tiny bit. But not worth sacrificing a lot of other stats for.

All fcr does for frozen orb is make it come out sooner, but no matter what theres always the same cooldown length between casts
