World of Wacraft has a lot of major milestones, many of which are punctuated by achievements, cool titles or flashy mounts. When I first started thinking of this subject, I assumed reaching level 80 would be my proudest WoW moment, considering it was the first time I reached max level. I started playing WoW during The Burning Crusade and leveled very slowly, spending way too much time in PvP, which didn't reward experience at the time. I took a couple of breaks and didn't hit max level until the early months of Wrath of the Lich King. But in retrospect, I recalled my thought when I reached 80: "Okay, now the real game begins." My next thought was that the moments that my guild first cleared Naxx-25 or Yogg Saron or the Lich King might be the pinnacle of pride for me in WoW.
Then I realized the truth. The moment when I probably felt the best about my WoW self was when I finally matched (and eventually beat) the gear of my best friend who plays and could beat him in duels. I'd watched this rogue friend, from BC to Wrath, stealth around and slay countless foes in battlegrounds, arena, and world PvP. I'd seen him win 2 of 3 duels against the very best-geared rogue on our server, and I could beat him. That was awesome. Plus, a bit of friend vs. friend gloating didn't hurt the ego.
Has there been a point where you thought to yourself, "I have arrived ... at awesomeness"? What achievement or event is your proudest WoW moment?
