Viking Units overpowered?

[caravel]

Indeed, but in the Viking campaign, Huscarles, both Saxon and Viking, seriously imbalance the campaign. The Northumbrians, Saxons and especially the Mercians are far easier than they should be because you can storm the Huscarles in there and take most of the map in a few years. Fyrdmen (equivalent to Feudal Sergeants) also help to tip the scales way too much in the favour of the English factions.
