I've been playing through the WoW TBC Anniversary preparation phase alongside thousands of other players, and one thing has become very obvious: most people are approaching reputation the wrong way. Are you planning to rush to Level 70 first? Or are you still unsure which factions deserve your time? I can tell you from experience that reputation is actually more important than many players realize. A good reputation strategy will unlock Heroic dungeons faster, give you access to powerful enchants and pre-raid gear, and make your entire endgame journey much smoother. So before you start grinding randomly, let me share the roadmap I wish I had when I first stepped into Outland.
