Theoden. Is there any reason to ever choose him over Gimli in a draft game?
1. More than a choice betweeen the two sides of a character seems quite obvious... how sad!
Why would you want him in Mordor?
2. To waste a turn (in a game where timing is crucial, maybe it can be useful at times. Rarely, I'd say, but still possible.)
How involved was Knizia in the design/testing?
3. He hasn't designed the pieces, but playtested them (according to what you can read on the Internet, at least).
