Thats the trick with this map, you need to know where the chockpoints are and where to lead away the attention of your opponent. I thought it would be a very interesting map to try out some basic zone control...
You had control of the center for a while there, but you chose to focus on air over sea, leading to the fact you can easily lose that zone. It was an interesting attack on the right there, but none the less when it came down to it, putting your Tank to the front was a bad move. With this, your recon action was a good choice for a forerunner but after it should have been some rockets and perhaps some airsupport. With this you could have cleared the area for your Tanks to move in quickly...
Also the fact that you chose to spawn some Copters over land units kinda was a fault for the Center. Battleships can't target Air, as soon as all possible targets were removed, I could easily move them to the right for support in clearing your ranged units...
My playing YoYo games with the battleships gave me control of the center, and using an Aircraft carrier as a midpoint for my Transports gives me an additional staging point for safety for bringing my infantry in, as you couldn't target the Transports while they were docked on the Carrier....
Plus also, I have been wondering. As you haven't used it once at all...
You do know how to use CO powers right???
