Many of the citizens out there aren't in the loop with the development, they spent money on an alpha game and then bitch and complain, having no idea about Server meshing, quanta, quantum, all these back-end techs that are being put into the engine so we can have thousands of players in the same responsive dynamic universe. In the next year or two we will see it come alive with more systems, Nyx and Pyro, more players and bug fixes. The servers are over-stressed because right now, a single server runs all the assets, cities, outposts etc. in a place the size of a solar system. Azeroth would fit on a small section of one moon for comparison. Many 'bugs' are simply going to vanish once this tech is launched, and the remaining bugs will then be worthwhile to troubleshoot.
