Ignite is broken

And by broken I mean broken, not overpowered.

In the last month or so I notticed my Ignite doesn't cast pretty often. It drove me mad af. But yesterday I saw my model what it is doing when I'm spamming it when my target it barely out of the range. It was making the same animation as if I was spammig my taunt (or w/e) - so I came into this conclusion:

Normal reaction of the model is, if Ignite is casted on a target that's out of a range, that it would go to the target to get in the range. BUT there's a bug that causes this movement command to get canceled instantly and it looks like the model is glitching.

Did anyone nottice this too?
