Battleground editor usefulness?

[Strages Sanctus]

Do he houses count as obstacles? I couldn't see any other obstacles to place. Also what does the battle tower do? It just created a blue glowy particle effect.

I think dominions MP could have a whole nother level of strategy if the place you fought had a greater impact.

Flying units would obviously have greater advantage in a obstacle heavy area. Archery untis would have little effect in such a place etc...
