So. The Sea-Kings, the Saxons. In vanilla, a very infantry-centered faction, a trend that we shall likely be keeping up (perhaps with the addition of some new units like axe-throwers?) Probably the biggest change that needs to be made is giving the Saxons a much stronger navy, followed by the need for a fresh new set of infantry. I'd like to also see some sort of "gimmick" (akin to the Romano-British being able to recruit Gaelic units or the Franks progressing from infantry to cavalry) for the Saxons - perhaps something relating to their legendary seafaring abilities? Another question - should the Saxons be able to horde? They are a bit more of a settled, traditional faction than they were 150 years ago, so we should keep that in mind. Finally, as always, for inspiration I am providing the default Saxon unit roster:
Infantry
Barbarian Peasants
Levy Spearmen
Chosen Axemen
Saxon Keel
Hunters
Saxon Hearth Troops
Cavalry
Mounted Nobles
Saxon Sea Raiders
Warlord
Navy
Boats
Large Boats
Pirate Ships
