Wanted to add this to the Dáin discussion, I planned to put it on General suggestions but it is all about Dáin, so I'll put it here:
I wanted to say something about Ring Heroes. Currently, I feel most of them are awesome, and I can understand the Witch King not having new abilities because of his debuffs to the enemy, but I don't feel the same about Dwarven Heroes. Currently, when I play Iron Hills, I try to avoid taking the ring at all costs, because even if it is a defensive faction, he feels like he's only useful for Fortress defense because of his 50% losses if he's not near an enemy building. His other abilities are awesome, and being able to train units from the Hall Of Warriors instantly is great, but I don't know, maybe Dáin should have fewer debuffs. Ring Heros are, if my beliefs are correct, meant to turn the tide in a game and give advantages, it is strange when you can't use this Hero except when he stays at the Fortress, making him as static as the Scholars in 3.8.1 Imladris and Erestor if I recall correctly, that were always in the Fortress.
Just my opinion, though. I believe normal Dáin's abilities should be reversed to 4.3, and I wanted to add this about his Ring Hero form. Anyways, The Edain Team always does a great job, and I love that!
EDIT: To add something more, I don't feel Erebor Ring Dáin is like Iron Hills, his ability to double allied units damage it's great, and he is going to be with the army anyway in his current role, so he's not as hampered (I believe that's the word, correct me if I'm wrong) as Iron Hills Dáin.
