This criticism is not constructive at all. Perhaps Blizzard would take player feedback more seriously if we conducted ourselves more maturely as a whole.
I am still holding out hope they will reveal they do intend to support wrath era servers in some way. Maybe they wanted to see some feedback before making the decision. I also see the original “no plans” response as a business strategy to sell more cataclysm bundles.
Linked below is my idea for how Blizzard could support wrath era servers, see “Argument #2”. The main idea is new wrath era servers are opened that people can transfer or clone over to while the current realms move onto cataclysm. So some people might transfer to wrath era and find their name taken, but a character rename is a small compromise for getting the wrath era server we want. If you go to wrath era but then months later decide you want to play cataclysm, you would have to purchase a server transfer. Blizzard can profit off the people who choose to clone, as well as the players who thought they wanted wrath era, but later realize they don’t.
