In fact, if you are completely Karazhan geared, you most likely won't be replacing your gear until you hit level 72 or 73. This is a big difference from the transition from WoW Classic to the Burning Crusade, as players with Black Wing Lair gear started replacing their epics as soon as they started doing Hellfire Peninsula with random green item drops. In Wrath, however, your epics will last you quite some time; the same goes for Arena gear for Seasons 3 and up.In Valgarde, players will be re-introduced to Tirion Fordring, who is now the new incarnation of the Ashbringer and wields the legendary sword. Fordring has come a long way from when you last saw him, and he now leads the Argent Dawn and the Knights of the Silver Hand against Arthas. Unfortunately, the two factions have merged into the Argent Crusade, giving you (you guessed it!) yet another faction to grind up from neutral to exalted with.On the Horde side, the first place you will see is Vengeance Landing, a site controlled by the Hand of Vengeance, a faction of the Forsaken sent to Northrend by Sylvanas for the specific purpose of overseeing the release of the Forsaken's "New Plague," which Horde players have periodically assisted with via quest lines. Some of wow gold players know where that plot thread eventually leads, but I won't spoil it for the rest of you. Just like the Argent Crusade, the Hand of Vengeance is another faction to grind up to exalted, with some decent rewards for doing so.
