Yep, Ein has worked hard for this and went through many phases before reaching a conclusion regarding the final form of the mod - or should I say the concept around which it should revolve.
Actually his timing can't be worse, as the VI era is nearing its end. Anyway, mods directed at MP can't attract many players to use em, mainly due to laziness and fear of the unknown (some people can get really frustrated when their world turns upside-down ).
Most mods demand learning a great number of new units, or in the case of CBR's excellent mod, adjusting to a new niveau and style of playing.
Ein's mod is very enjoyable because there are only 5 changes, no additional unit learning for the lazy generation :
1. Higher prices for powerhouse infantry
2. Faster speeds for fast cavalry, Lancers become slow
3. 40-men and 12-men infantry become stronger.
4. Mongols in high period
5. Same units with different graphics are removed( ck and teutonic knights for example, as well as order foot soldiers,which remain only in hte form of italian infantry-exclusive unit)

Changes requiring not great modding skills to make but an eye to retaining the form of the original game and turning a valour level down those nasty swords, making em more vulnerable to cavalry and thus demanding the presence of spears and anti-cav. This idea has been the core of many mpmods, it's just applied differently in this one.

In effect, the mod in 10k lowers the base morale standard to 6 from 8 tho it s purely up to the player if he wants , say, to keep v2cmaa as his main infantry, paying for them around 1300 florins IIRC. Only cavalry and 40 men units will be able to get mrl 8 for less than 800 florins. So spear and sword mrl is more close this time, with swords having still an advantage vs spears but being unable to rout em without significant losses.

The question of having a better mongol horde has risen up as well. Altho I personally believe that the horde is well equiped unit-wise to handle large plain map situations, the fact that the retreating shot cant be reproduced in MTW engine is naturally the greatest problem in depicting their real might, without resorting to mindless cav rushing if the opponent is eqiuiped with lbs and many pavs.
Some ideas have popped up like mongol horde warriors getting a lb..
Ofcourse the mod is still in progress
