works on langres in 1v1
That map isn't really balanced with CoH2 gameplay in mind.
None of the CoH1 maps is good for current armies due to how they work and this one is full of possible abuses.
Bunker on north cutoff? Maxim spam? Snipers working on extremely open map(who would have thought it'll work here!), 251 with grens snowball push, base to base artyfest.
Relic was lazy with implementing this map for 1v1 instead of creating the map that actually suits CoH2 gameplay.
Just compare this map to Kholodny and you'll know what I mean.
Have you noticed that worst things that happen in 1v1 are mostly on this map?
