I usually just ignore them.  Considering the amount of effort it takes to get Alliances, it's not a very good deal.  Pretty meh.  Without anything to make them special, there's no point in spending the money.

The wage override (if not 0) will descrease the wages of the knights, I think that tag only works for positive numbers (I could be wrong), but I have changed it to 1 and got knights costing 3.5 gildar per season instead of the 9.2 I was seeing before. I'm sure other values will change that cost to a more reasonable wage for all, unless the real intent is to not have wages at all (then the above is the fix for that particular problem).

My point is that I should not be able to easily construct identical units.  There isn't anything about them that makes them really special except having Endurance II.  I think they should have special armor and a unique weapon (perhaps a lance, which can be used with a shield)

Download the file, place it in the mods folder in the My Documents/My Games/Legendary Heroes directory, start Legendary Heroes and enable mods in the options tab, restart the program, and start a new game.

Unless I'm mistaken, Knights of Asok are mounted on Warhorses, so you're not able to construct identical units unless you're playing a faction with the Legacy of Serrane trait, just units which are so close to identical that it makes no difference.

That would be nice, particularly if combined with an ability which granted additional attack per tile moved to simulate the benefits of a cavalry charge.

Maybe a more powerful Knights of Asok befitting the later game Alliances tech could be included in the next version of LH?
