I see most of the complaints coming from people who are ignorant (not using that word as an insult, but a description.) This game brought about a new sort of player to the "MMO" community, I believe and from what I have read it has brought in more "single" player gamers. These people do not understand the vastly complicated mechanics of MMOs. I personally believe that Trion understands this and takes this into account about bug reports, foolish reviews by amateurs, and other uneducated people; however, I do not mind so much discussion about bugs on the forums. I believe it is important for the players to be able to vent their frustrations and share their criticisms with one another. From my understanding of Trion they are one of the few companies that still take their fan base serious and want to make them happy within reason.
With all of that being said I will say this, I have beta tested games sense 1998 (starting with EQ). This game was not released beta. This is by far one of the cleanest launches of an MMO that I have seen in the thirty years of MMOs (if you want to be technical about it), but vastly believed that it is only sixteen years old. Which every number that you want to recognize of the age of MMOs, this is a very clean release.
