Hunter Noventa
Overlord
Perhaps they could add a scout-like unit that could build an outpost much like the worker does now, only the outpost has a border, probably only 1 tile. It would function as sort of an uber-colony. Say, it could work the tile you built it on to build defensive structures and units, and if you put it next to or on top of a tradable resource, connect a road to it and you have it.
