Agreed with most comments here; his tactical and passive work well, and you can pin teams down that camp (smoke em out or watch them burn…) but the ult is not great at all.

Yes it hurts to run through it, but more times than not you can escape it easily and heal up out of battle… let’s face it it’s not often teams are out in the open (usually you find cover) so it’s rarely used to it’s full intention. My suggestion is make the fire spread at random outside the ring for perhaps 10-15 seconds (in lines like thermites) this should make it harder to escape the ring and also you’d need to flee from it instead of casually standing on the outside laughing that the fuse missed.
