True! Especially Galadhrim were ever watchful, they used their flets to look out for the enemy.
Concerning the siege mechanics:
Could ropes as a siege engine be made on the SAGE engine? As I've proposed earlier, would that be possible?
I think that a different type of ent for instance a battalion of three smaller ents similar to snow trolls would be perfect to make a more broad choice of siege weapons without adding to much more to 2.0.
