I have come to conclusion that in solo games, you are cheating yourself badly if you do not play Spirit (Particularly Eowyn). I am tired of building cool thematic decks that only let me down substantially in the quest phase because I haven't added Rohan and that damned Sister-daughter of Theodin. Any other solo players feel my pain?
Don't get me wrong, I LOVE this game, but I want another good questing option outside of Eowyn! If I want to win consistently, I play Eowyn. If I want to have fun tricking out different themes outside of Rohan, well, I usually always lose.
