Playing it for a bit now and I really enjoy it.
Got some suggestions tho,
1. Battle maps are in some cases far to big. ( Enemy just stands there while you have to take you troops all the way or solo their commander so they will attack ).
2. Players villages should be attacked less. Its impossible to get money from your village since its always under attack even tho other closer to enemies remain intact.
Recently after fighting 5 enemies around Wolfs Edge ( The North ) my village got raided by Balon Greyjoy ). I know its not just ACOK problem but it seams bit less annoying in native.
3. North needs some better path finding aswell as Dragonstone.
