Hi ! I wanted to help at least a bit by saying motivating shit !
I've read with attention all twenty pages of the post, which is something I do rarely, and here is what I think : This should be ranked. I'm thinking like Rohulk, having really really hard maps is good, because its motivating. Having maps you look up to, that you dream to do, is what makes you going.
"It's too difficult !" some say, I'd make a simple comparison. At first, humanity didn't even have fire, now, we've reached the moon, and I know that soon we'll reach the stars. Tell any prehistoric man that their descendance will reach the stars in the sky, I'm sure they wouldn't believe you, yet we're close to it now.
When I see something hard/seemingly impossible, I think 'what makes this look impossible ?... Oh, it's that and that, but now that I think about it, it's perfectly doable !'. I personnally believe that someday, someone will SS Centipede all mods, and when that day happens, this map will have been SS'ed all mods plenty of times already. The only way to improve it to challenge yourself. Let's improve the mapping meta by making and ranking this kind of hard yet well made maps !
