I play a lot of LOTR Card Games since almost the beginning (release of The Hunt for Gollum in french). Like thousands times in one and two players and 50 times at three players. I just stop play at four players because it is too long.
I build a lot and keep to update and play all the decks I own. I always try to get the best deck around a specific concept, no matter if I always play the same powerful cards. Since a nightmare deck is out I never play his normal scenario and I love play over and over the most difficult scenario.
