The lag was no where near as bad as the axis vs Oren battle.Β
A lot of players who fought with the orcs were happy winning the wheatfields when there was far more lag present. They didn't complain then so I don't see why they'd be selective and complain when they lose.
M&B warclaims would be sick, Axis v Oren warclaim literally crashed the server so I think the devs have managed to make some small progress. Or the scale of this warclaim was just significantly smaller
