There are some bugs that make the mod very painful to play imo:
-troops being blocked in the midst of enemy troops, not being able to attack and taking damage, that happens most of the time actually in battles involving more than 3 batalions. commands just don't work in these situations.
-archers not being able to aim from a cliff which makes ambush/strategic positioning of archers non existent in the game
-graphics taking so much ram it's impossible to play w/ 4 players even in low
-ai difficulty kind of stressing and just consisting of the enemy having a lot more resources than you at the start..
-i've already posted before about my bug w/gondor (one of the main powers don't work, which ruins the synergy of the faction)
in resume, the mod is very well thought in theory. all the different factions are interesting to play and offer rewarding combinations. in theory. cause in practice, the game is still not running well to be fun in long term.
