It would be good to know why yopu dropped this one. Something lacking that you thought you couldn't fix, or just got bored?

I asume that you share beacuse you want to bring it back to life...
I like how the middle path is dangerous and I think there are enough entrances to the high ground to not make siege tanks + tower imba. Rather, it creates and interresting situation. I woudl, however, have a small sneaky path on the outside between fourth and gold. Perhaps DSR-blocked.
What's the idea with he top and bottom middle expos (third and fourth)? They are so close and the ramp between those are so wide it looks like one player effectively denies the other player his third by taking the one on middle high ground and defending it. Intended?
I can see why the gold base is gold and niot regular, being so far from the main entrance and off the main path. It will be very easy for T to FE to it and gain an advantage .. or even take it from start? I would make sure the gold lies along a possible route on the map, perhaps intersect it more with the high ground .. force players to pass the gold if you want to take the widest ramp up to the high ground.
You'd probably thought about adding DSR rocks to the gold and decided against it it beacuse the it's off and by ground far from everything ... thus no great advantage taking early .. right?
Post to TL thread btw, if there is one, or post more info.. rush distances etc.
