I like the idea - actually a LOT.
This medieval Battlefield 2 hopping game with 13 yr old agi girls wielding heavy polearms without fatigue and faster than the eye can follow... is sometimes fun, but also kinda tiring.
But like Macropus said: not much of a chance.
Mod is on its decline, dev ressources going into the new game, Bannerlord coming up, player base is already going down... so I do not see any sub-mod coming...
Maybe one of the mods for the new games (Bannerlord or M:BG) will take up the idea. But I doubt it, real combat sims always attract only a very limited number of players, most are in just for the lulz (nothing bad with that - me too ;-) )
