There is a small vocal group of WoW players who feel that Burning Crusade was the pinnacle of the WoW experience, an unparallelled beauty of game design, and that life has gotten progressively worse ever since. Those players are starting to piss me off.
The reason they like BC so much is the same reason most players like an expansion more than all the rest: because that's when they started playing. Vanilla players like to talk about how hard yet awesome life was in our day and Wrath newbies (who, appallingly, are old timers themselves now) like to talk about how the game has only gone downhill since their time.
All of us old timers have one thing in common: we look at our glory days of exploring WoW for the very first time through rose-tinted glasses, remembering all the great stuff and glossing over just how bad the bad stuff was. But these BC lovers have crossed the line into being just plain daft, and trying to claim the exact opposite of how things really were.
Because really, BC sucked.
