I've beaten the raid on hard around 10 times or so half of those times I played it all the way through with no exploits, then I started to do it to save time. I have some friends who cannot devote a whole lot of time to playing the raid on hard so it is a lot easier to just glitch the bosses and help them beat it faster. I do agree that they should patch it and I have no problem beating it on hard (besides time maybe).
