Well said Theo.
I wonder if Relic ever gonna take the advice we gave them in their own Map improvement poll. We stated the most obvious issues there like the Kharkov cutoff on the left side. I bet some of these changes could be implemented with the map editor within a day's work. But this thread is from Nov 29, 2014 which makes me wondering a little bit.
Since Relic is/was working on other stuff I wouldn't wonder to be honest. I think the next balance patch could be a suitable momentum to implement map changes. Maybe they had no better opportunity.
And adding something like Duclair would indeed enrich 2v2's map pool with a balanced map, GiaA. Most of current 2v2 maps promote blobby, bunkery and non innovative gameplay and build orders due to their tremendous lack of flanking opportunities.
