idk I think mid is more advantagous for CTs because you can sometimes only see the head of the guy upstairs at the door or a tiny pixel of him, he can quickly dodge fire so get 1 kill with awp, fall back, repeat. sure you can flash but most people can't do it, or miss the timing. I just throw it over the wall when I'm close but the ones at the door just fall back so only really optimal for people being at the stairs or really close. Havent played after changes yet though. The little corner is also not that easy to clear since someone can be at the left side as well.
