What Dekadenz said: Really could not care less about how long somebody's been playing when I've seen almost a dozen people with Hand of A'dal titles get killed by Bruce the crocolisk, Goredome, and Vishas at Rank 1 in the Brawler's Guild lmfao.
Other than that: I've transferred accounts, so I go by PvP titles. Anybody arguing about "you could've bought the account"... well, those people are either just being cynically humorous or will never be happy. Probably saying it in jest.
Not sure if it counts, but itemwise I still have the Holy Mightstone in my bank. This was an item which gave 300 Attack Power en 400 spellpower vs undead.
Also have a Quel'Serrar in my bank. 3rd acquired on the server (horde/alliance).
