One thing that bothers me about MMOs is they try to be everything for everyone and we all know the parable of what happens when you do that. I would rather have 2 or 3 niche MMOs then a bloated MMO that tried everything but did it poorly.

For example, in LotRO you can easily solo to the level cap, but once you get there progress comes to a screeching halt as content becomes more group based and difficult. So essentially you're playing 2 games, one thats super easy from 1-60, and one that becomes more cumbersome and difficult at cap. It would be nice if Turbine had a clearer vision for the game rather than this sort of bipolar leveling system which gets people all fired up.
