"We didn't have WoTLK Classic Gold any people thinking about how social systems ought to function the time we made Wrath of the Lich King This is a brand new way of looking at certain things" Zierhut said. "What can we do to promote social? What can harm social? Paying close attention to that...We're trying to consider when we're designing for Wrath of the Lich King [Classic] how we can make social more enjoyable, ways to create situations where people can find commonalities, engage in acts of reciprocity, the things that lead them to friendship, and avoid damaging the social connection. That's something we didn't think about when we first started working on Wrath of the Lich King the first time."

Other changes that will be implemented are the result of Blizzard having watched Wrath of the Lich King play out once already and with Zierhut making use of this game's Death Knights as an example. In the beginning, players who wanted to become a Death Knight had to play to catch up in the days after the launch of the expansion, because the class began at 55. Meanwhile, everyone else who did not make the Death Knight was already level 70 and heading to Northrend to try out the new content. Blizzard will not be in that situation this time in the form of Death Knights coming as part of the expansion's pre-patch. Although Blizzard will not confirm an exact length of time for the patch, the idea is to have it last somewhere between buy WoTLK Gold two to six weeks.
