Esxile made the fundamental point that there is no excuse for launching COH3 without providing a 'Scheldt' from the get-go. I have never played Scheldt but I do know (and I am reasonably certain that you do also), that SP was the majority of the base for COH1 - people that were never seen in MP and probably never even signed up to gameplays.org or this site.
I fully realize how much AI casuals love this map, its their blood and bones.
But it also can not be denied how small multiplayer map pool is, especially since all the maps are exclusive and there is no map overlap between the modes, which made CoH2 look like it had much more maps on release.
