Romans II for sure.

The real weakness in it though is that you have no dependable scout/anti ranged units. You are going to find yourself caught in a bit of a crossfire with your Romans, trying to determine whether or not to break fromation or stick together, and if DW 8000 goes down, your disorganized Romans are going to be all over the place trying to hunt down enemy ranged troops if your opponent has good ranged and plays it smart.

Honestly, I would scratch Fen Hydra, and replace with Krug. Why? Because like I said, your real weakness here is getting picked apart by ranged, and whereas Hydra will likely get weaker and weaker as it approaches pesky archers and ilk, Krug will be eating arrows and bullets as energy bars, and make the crossfire strategy somewhat unattractive to your opponent.
