@Tkragon Few comments:
1) The entrance on border patrol -
This is a bad idea and will ruin the map. I know you were trying to go for a certain feel with it, but it ruins the map from my experience.
It's a very tiny entrance way and it's the ONLY way to enter through land. This destroys the flow of gameplay and also heavily favors allieds over soviets. It makes scouting useless (as teams will have the garrisons early halting any early scout, especially from a soviet player). It stops the flow of any land units. It's very easy to build towards and set up shop and once a person owns the middle/cliffs, the game is essentially over.
Essentially, it gives the map a 'gimmick' feel which is what aWarZilla was saying when it becomes another 'rekool' or gimmick based map. The map is SO camp-heavy due to the entrance, that the game becomes who can suicide kill their opponents oil derrick first wins.
A potential solution might to just widen out the gap. That way, at least, if the soviets can somehow kill the garrisons, then they can maneuver past it. However this is still dubious. Maps with one small guarded entrance just aren't very successful.
2) You guys are saying CS is mirrored? Maybe my understanding is off, but the reason why CS is unfair is directly because it's NOT mirrored in terms of ore per side. People love the mirrored parts of CS but hate the fact that the ore is not mirrored.
3) I think creating a balanced non-mirrored map is a work of art and ultimately the most aesthetic and 'cool' maps are non-mirrored. However, mirrored maps are efficient and great for their purpose, so I'm a fan of both.
4) Your Woodland plains map has A LOT of potential. I think that could be a huge hit.
