Im going to have to agree with Noxid and Raigen. Yes soloing them will take time but thats expected, higher level black doors are supposed to be done with more than one person. This is not to say they have to be in the same party. Even several solo people can clear one in less than an hour. Yes grinding high level doors is a pain in the ass (we all know this). Decreasing the amount of mobs on the floor? Thats just making it too easy in my eyes, if anything 7 mobs on a floor is pretty reasonable for high level.
