England is probably the most dominant faction in the game,despite being at war with about 4-5 factions it can handle itself really well.They ended their war with France by smashing their way into Paris and Orleans and taking it whilst wiped out the Welsh and nearly eliminated the Kingdoms in Ireland their only loss was a castle to Scotland and they made peace after,and almost forgot about their constant campaigns with nearly 10-20 lords.
I think it is because England (apart from their size) have the strongest lord-marshall in the game - Sir William Marshal.
If I'm not wrong, England ''sweeps'' through their opponents because marshall Marshal manages to lead a very long and effective campaign.
I already mentioned that ''problem'' before, so Korinov decided to nerf Sir William for the next release of the mod.
But bear in mind it is possible that:
a) my theory was wrong
b) my theory was right, but it will not have such a big impact on gameplay
