Geez, a lot of "blind" people here!...
I was already massacred several times by Shang booms, in mostly Continental maps.
One of the times it was the creator of the boom himself that did it to me.
Shang is U-N-B-E-A-T-A-B-L-E in a 1x1 on a map with water (so that they can fish-boat boom).
Right now, everybody is experimenting and the room never really filled up.
There are posts in the Shaitans forum dealing with Shang and even an interesting article by Thump on the subject of Shang (read it, it's good literature).
In conclusion: If you play a lousy guy like me and I'm Shang - then you will be saying, "Haha, so THIS is Shang's power? No big thing, they were all wrong." . Just go out again and play someone really GOOD with Shang! Wow!
If you play a worthy Shang opponent 1x1, you will have no chance at all, unless you are Shang, or you adopt the "anti-Shang boom" measures that Thump and others talk about...
My 2 cents.
