Can we make it so that this talent doesn't fire without a target at all? Or even without a target in LOS :p I'm not even sure what's the point of it but currently, if you are near a wall and cast freeze at a point inside the wall itself, you'll kill yourself because somehow you targeted yourself then without any warning at all.
Also, the cooldown is halved when use on a friendly target? Nice but I think the damage needs to be halved too or more

This talent hits hard.
