Good points, but a lot of the maps are fundamentally flawed. Things like overcrowded areas, weird structures that look good but lead to terrible gameplay (eg. the castle on eindhoven which is actually a decent map overall), weird ressource layouts and the terrible use of houses make some of them unsalvageable. Those maps shouldn't be bothered with let alone put into automatch. (Lost Glider, Westwall, Ettelbrück, Trois Ponts, Poltawa, Charkov etc.)
The process you're describing needs to be applied to well thought out maps that need fine tuning but offer a good basis. (Kholodny, Langres, the 2v2 map with the 3 houses around the southern fuel that are sort of ruining it atm etc.)
Just a FYI: Eindhoven was revised 3 years ago by Spanky with input from others like Cruzz, Carpiqua and WhiteFlash. However, probably owing to team changes at Relic base, the map never progressed further.
