Just had a little look through your map, and I really love it. I especially love the redesign of the layout of the map, and the internal keep. That being said, the map is far from finished. I'll list everything I could think of in my brief 20 minute look through the map.
The biggest issue right now is that the defending player doesn't have nearly enough build plots. The defender needs at least 4 more build plots to stand up against the might of 2 attacking players. I would recommend putting 2 in the inner keep, 1 in the courtyard just outside the keep, and 1 more behind the deeping wall.
In addition, the defender should start with 4 heroic statues placed at key locations that also give the full discount on heroes. A statue is needed in front of the main gate, in the courtyard, and 2 behind the deeping wall. Some wells would be nice as well.
Next, the command points are still standard, and should be balanced as they are in your Minas Tirith map.
Next, there are several units that are not properly balanced to the current version of the Edain mod, namely the 3 units summoned from the Rohan close combat herald. Their stats are great at first, but suck terribly when upgraded, even compared to peasants. Related to this is the Rohirrim reinforcement army, the captain leading it is extremely weak, and the army itself cannot receive any upgrades besides heavy armor. Finally, I'm not sure about the Galadhrim from the Inn, you may want to double check them to ensure they are properly balanced.
Next, the system for summoning the reinforcements isn't terribly clear. I knew how to do it because I watched the video, but a LOT of people will get this map without watching those videos and waste the heralds that summon the reinforcements in combat. I would heavily recommend adding an objective for the defender telling them to send those 2 heralds to the light beacon to clarify this.
Next, I think that Théoden should automatically be freed from corruption, since you cannot make use of several of his corrupted abilities. Additionally, I think the cost for the 3 hunters (Aragorn, Legolas and Gimli) should be reduced, as they are so instrumental in the Battle of Helms Deep. Right now it costs a fortune to get the 3 of them out at once, on top of all the other heroes that you can recruit. Also, do you think you could create some custom abilities for Grimbold, Elfhelm and Erkenbrand, seeing as how you made them full heroes for this map?
Finally, I didn't actually wait the entire time to see the Galadhrim reinforcements, but I know from the video that they are cavalry. I disagree with this, because the cavalry used is taken from Rivendell unless I am mistaken. I think that they should be the first of the reinforcement armies to show up, and that they should be archers, the Galadhrim do not have any organized cavalry forces in their army. The 2nd army should be the Rohirrim reinforcements, and I think it should be made stronger.
That's everything I have so far, can't wait to see the map fulfill its potential! You are doing the Edain mod a service making these excellent maps for the community
