Twitch streams of hardcore MM NMA is constantly going. As it stands I think 4-5 streamers/day are streaming this category. There is already NMA, but it's hard to sort out who is hardcore and who is not.
As its a popular category that's being watched by the community on Twitch, I think it would help boost the runners by adding this category and might attract more to the runs as well.
We used to have MM and HC MM as separate categories, but since the route and the playstyle were the exact same, we decided to merge them together under just master. The other factor that contributed, is the lack of completed MM runs. And separating it further wouldn't help.
Fair enough, I guess I'll have to put some runs on the board then lol
