To be honest I don't understand the animosity most players seem to have for Theoden. His threat of 12 is rather high but his ability either in solo or multiplayer play is invaluable. Maybe its just the way I play, but if I'm running a mono-tactics deck solo he is the only option I have for a 3 willpower hero and that is the department tactics sadly lacks. He also boosts my other hero's up to 2 or 3 which can be critical. In multiplayer he is even more effective giving a global bonus to all players with tactics hero'. Even if there role isn't primarily for questing in tight spots or for the final push you might need all hero's to commit.
So I guess I want to hear some valid critics of Theoden and why I shouldn't use him. Thanks
