A lot of the changes in the past 5 years have really improved the game, IMO, and made things more complex and given the game a more unique feeling, especially in class design.
Even the zones have dramatically improved in quality and complexity, which is a very good thing considering what type of competition this game faces when you think about WoW and Skyrim. The same types of people who are drawn to those games are also the types Arctic needs to attract, so it has to compete if it wants to replace players it loses.
Also, I would suggest you focus more on learning the book loads than just trying to buy the books. At this point in the wipe people are selling, or just dropping, books that at an earlier point they would either never have done so, or sold them for huge sums. It's better, IMO, to learn the loads now so that when the wipe comes you won't need to rely upon others loading them for you and hoping they will sell em (and that you can afford it).
