Wanna know why roh is always the last one? He's so damn good at sustaining the hp of his horse and himself for a damn long time. If you start making contact with his horse as ranged, he's going to start bobbing and weaving until you give up from the loss of arrows. He's a tough target to hit when he knows you're gunning for him.
He mostly avoids the main infantry forces and archer concentrations for first few minutes. Like I said, picks off lost peasants, heads to spawn, skirmishes with few cav that try and chase him. Basically not much a factor while the main fight is taking place. Then he's left at end when the issue is usually settled, 80% of time one team has a huge player advantage over other, and if its his team thats lost he still fights for next 2 mins anyways trying to increase valor chances. He's just a pest not doing being much of a battle factor then annoying everyone else by adding time when they want to respawn in next round. Thats why you get kick votes and threads here.
