It never gets old to watch pro-Retail people worm their way out of Legacy logic and introduce their own spin.
Many said this, Many said that ...
The reality is the former version is no longer available to play. Blizzard and their overpaid lawyers may say they hold the rights, and thus nobody ever can play again. It's not going very well for them, it seems. For every one server that got shut down 10 more spring up. It might be 50. I look at the popular ones and would say 10.
Blizzard needs to come to reality and do effort to work with fans, and release an official Blizzard Battlenet Legacy Server. They are losing the battle, their tight reigns get weaker and weaker the more they resist.
Retail fans are funny. They really think Blizzard will give more content if they help deny Legacy (and in their minds force more to play a retail game that the people they are forcing seem to dislike). Haha more revenue =/= more content .. dream on, it's all going to other projects.
