Hm. Well, I know I'm going to get stoned for this, but am I the only one who's worried about a levelless system? It's wonderful, absolutely, and having a game that requires intelligence instead of money and time wasted is revolutionary, put lightly.
However, I can't help but hear the little voice of the fear of the unknown in the back of my head. All games, even GW, have had some levels, put there for various purposes. WoW was stacked, linear, structured and repetitive, but in it's horrible repetition was a cause; something to do, nay something you had to do, that kept the game moving, even if it was a fabricated and pointless path.
With a levelless system, I almost fear that it will be like a rat and cheese at the other end, without the maze between them. While the maze is pointless, it gives the rat something to do to earn the cheese. Without the maze, the rat needs only to walk to the cheese, without qualm or challenge. But then, the test is over. What more can the rat do? I'm secretly afraid that a levelless system will cause a lack of motivation. Skills are great but what if, eventually, you find that perfect combination of skills and weapon, to the point where you no longer need to earn more skills?
Consider GW. The PvP was fun, but it got boring. A 20 level system, with a small world to explore, and never-changing, instanced wilderness areas made the game obsolete and boring fast. The only thing that could be done to further entertain you was to create another character, and then that plotline never varied between the two classes.
Again, it's not as if I'm not all for a levelless system. Heaven knows we needed something different in this dying MMO market. These are just my latent fears. I'm sure Funcom can think of something altogether extraordinary that will continue to make the game fun. I really just need to stop thinking TSW=Guild Wars.
This could also be AMAZING! If the natural way breaks down then it will evolve into what the players make it. But then it will be hard to attain balance when mass population gets majorly involved. But this game was intended for a whole new freeroam.
