Kieran,
Sorry - I haven't really read enough of your posts to catch on when you are joking. Know what I mean? It takes a fair amount of reading someone over the internet (for me at least) to really catch humor ever time.
As for toasting him in a duel, it probably wouldn't change him. It would put a brief smile on my face however (assuming I took him in the duels), and be one more thing to clobber him with the next time he decides to mouth off.
As far as taking it seriously, within the context of AH - sure thing. People only have so much free time in the world. People spend valuable free time trying to have a good, competetive time in AH. If some idiot detracts from the overall experience, he's going to draw the ire of some people.
I guess the best way to put it is this - I probably can't change him, but I'm not going to hide my annoyance.
Dueling one on one does have its points. For example, am0n made it clear that he thought lazs was a substandard stick in the F4U-1 compared to himself. If someone like me, with zero time in the F4U-1, can hand am0n his bellybutton in that F4U-1 in the dueling arena, it goes a long way towards showing tha am0n's opinion in the matter is basically weightless. That's what I was getting at.
Kind of like k/d, k/s, any stat - dueling doesn't prove everything, but it does prove something. At least in my opinion.
See you up there,
