Let me introduce some of you to the most basic, first year of college PLC curve:
WoW has long since peaked and is in a decline, contrary to popular belief this has nothing to really do with quality, infact most products tend to improve as the manufacturer/developer makes tweaks to their creation. Chances are that Iphone 7-9 will be better than early Iphones in terms of speed, features etc but chances are also that Apple will lose ground eventually in the mobile market, that is natural.
Players have always quit WoW, even in classic, but they were replaced by even more new players coming in, thus you saw immense growth year-by-year. That is no longer the case, the game obviously is losing players but the main issue is that those players arent being replaced 1:1 by new players. The game is too old, been tried by most people who either fell in love with it or thought it was the biggest POS ever. There arent many people out there in 2012 who dont know what WoW is or whether they like it or not.
No the game wont die any time soon, no game killed WoW, so all you overzealous fanatics of WoW do not have to defend the game, it will be around for many many years to come. But it has seen its prime long ago, and is in decline, if you can accept that then your jimmies wont get rustled when you see a topic like this or any "negative" topic that you perceive as "OMG TROLLING OUR WOWZERZ!"
