From the mind of anet:
Q: We got lots of these new free-to-play subs before HoT, so how do we get them to buy HoT?
A: Make the elite specs so over the top OP that the free accounts will have to pay for HoT if they want to be competitive. Sure, some won’t pay but who needs those freeloaders anyway.
Q: Our main problem in wvw is server population imbalance. How do we push the megaserver from pve to wvw and keep the BLs full?
A: Give wvw a new, complicated BL that no one likes and thoroughly demoralizes the wvw community. Then, when the wvw population has bottomed out (and we raked in some extra cash as all the true diehards transfer to gold league servers) we unveil megaserver for wvw along with a really cool new map that brings everyone back.
