First of all, you aren't going to know how fun it is by a sample of a few hours. Second, there are plenty of people who are playing this game and enjoying it as it is now, while 2.0 isn't even out yet. Yes, it still has some problems, many of which can't be fixed until they transfer the data to a more functional client. Have you even SEEN the new UI in the screenshots? It looks almost nothing like what we have now, and probably has been built from the ground up to be better streamlined than (to put things brutally) the clunky crap we have now. There are a handful of things I hate about this game in its current state, the majority of which involve the server instability, but the point of 2.0 is to fix these problems. While we wait for that, SE is doing an excellent job of keeping us interested with the drastic changes they make in even the smallest patches.
The only reason I'm giving you the time of day is because you took the time to articulate an argument, but don't be surprised if you get a negative response for bashing something you barely know in a forum used by its fan base.
