I just thought of two.  On my tge at lvl 55 I think, there was a wiz named Blastt... some of you might remember him.  He used to wreck everyone in Fp.  I got back from a grind, wearing my normal HP grind suit and he challenges me to a duel at the arena.  I rep, duel him in grind gear with him putting his back to one of the poles.  I beat his arse no backstabs.  Had about 2 bubbles of life left, lol.

Other one was when I was going for my mc.  I was grouped with a  45 druid at Dshinn undead (guildie of the tank) who kept talking smack about how  he had an infallible strategy to beat anyone, and hed been beating 60 warrs, 60 monks, 60 rges, etc... I point out any possible strategy he has and hpw I can beat it, including the fact that I had a monster bow to kill his root, a no cast SoW to beat his kiting, etc... he won't give up his secret...So I tell him to meet me in FP when the group breaks.  We go back by the well (this is well before lyco forms btw) and he goes pixie and puts his back to it (surprise)!  Timer counts down 5 4 3 2 1 I cast a wound and hit attack as his guildie looks on... I think he took the wound and 2 hits of the quad before crumpling.  I asked the tank "Do I have something on my shoe?" in say, lmao...
