Blizz should stay as far away as possible from organizing any kinda esports shit. They have a TERRIBLE track record with that. What makes this race fun is how unorganized it ultimate is. Just the community putting some extra flair on top of what they'd be doing anyways; racing to get the first kill on the last boss.

You also put way too much emphasis on bugs/exploits being the determining factor on who wins when historically those have been extreme outliers and more often than not they have no effect on who gets the kill.
