I vividly remember beta threads from the early 2000's in an german forum and even with 80 - 85% rated maps it was more like "Change this, change that, that is S*!%, that sucks, do it like this."
That's how we all learned mapping: By getting that exact kind of feedback and listening to it.
For AMC-Modular, I even felt the urge to clarify that I actually like the map a lot besides all my criticism. I wouldn't have written this final part back then at unrealed.de, and still noone would have wondered.
Anyway... My map is final as well, see here: DM-AMC-Gluon
