Spyro, well done.
We need more maps like this. Its open enough to allow for tactical movements, but has cover and obstacles for all sort of tactics. I can this map being played many different ways each time.
One important thing is that mountains and hills act as obstacles, but you can actually walk over them. One things I find really annoying in other maps is that hills and mountains basically act as walls. But by allowing players to walk over them, it really opens up the map to all sort things.
The forest. I really like them. They actually feels like a real dense forests once inside. Although I can see this being a framerate issues with a full server, try to keep that same feel of the forest as much as possible when optimizing it. Also I really like how mechs can traverse the forest patches, but tanks CAN'T. I don't know if that was intentional, but if it was its a nice touch. In fact imo that should be a feature for all maps from now that include forests.
A couple issues though.
The shrubs in between the forests are eye sores. Their view distance is really close so they keep popping up all over the place and changing shapes. Its really distracting and detracts from the overall aesthetic of the map. I would say just to get rid of all foliage between the forest patches, and put just grass and the occasional tree. Also it seems if you get too close to the southern volcano you are suddenly considered outside the maps and it kills you within 5 seconds. I usually always get killed while walking down there. The occasional pools of water you find throughout the map look like swimming pools. I say just to get rid of them if there is no way to change the color. They look silly.
All in all, good map.
