Sounds like a pretty good deal for $10. While waiting on RotHC I dusted off LotRO for mid week gaming and spent about $15 worth of points(I bought them on a double points sale normal price is about $20ish) just for the Rohan landscape quests. If I spend the same amount I can buy access to one raid and a couple of 3-6 man dungeons that make up Rohan's endgame.
SWTOR's mini expansion actually seems like a good deal. If it was $40-50 it would look really thin, but it cost me $10 so far it looks solid.
