The best memory I have about Vanilla is winning a duel against another Mage of my rbg team.
We was pushing rank (the other mage wanted to push r14 when I was only pushing for r11, sorry didn't remember his name).
We created a team in warsong with few mage, to oneshot the flag. When we waiting for the proc, we were all in front of IrongForge, dueling everyone.
Then the other mage sayed on TS than we was the best Mage of the server (or something like that). I remember said something like 'you can't beat me in duel'.
So the duel comes and I crush him in front of all my team. Of course he had a better stuff than me, and I was so proud of me.
We did more duel in the future, he never win one.
PS : sorry for bad english
