"In the good old days, expansions came around once in a blue moon. They were the stuff of legend which invited almost two years of hype and intrigue. You paid your dollars/pounds/euros/yuan, and you got your new classes, those shiny new zones and those ten extra levels. But, with patch 3.0.2 (aka Echoes of Doom) we got something new, we got transition. Yes, this was the patch where we got a sampling of Wrath designed to tease players waiting on tender hooks and also keep interest for that final week until the expansions hit properly.Given Blizzard's shift in how they treat patches, now geared towards larger mini expansion style updates like patch 2.4 and patch 3.2, there's definitely something changing in the way we get new installments of the game. After all, there's as much hype about every mini expansion-like patch, from the new areas, class buffs/nerfs and weapons to the smaller changes involving the UI. Shiny expansion special editions aside, do you think it would ever be possible to have expansions become automatically downloaded massive patch updates over a standalone disc or download that you have to buy every two years? What do you think, readers?"^^<http://www.w3.org/2001/XMLSchema#string>
