Master of Arena! Or if that's too much Arena for you, Master of Closed Maps would be a nice change up.
If that involves too many walls, I also liked the concept of "Wandering Warriors" hosted by T90. Nomad style maps are, in my opinion, the most interesting and unexplored style of RM AoE2.
If Arabia or similar is more up your alley, I suggest going with classic (Voobly or HD) Arabia. Cliffs, more wolves, no rhinos or elephants, no starting sheep at the tc, lakes in your most convenient woodlines, and, yes, imbalance. But more fun.
