So CCP are wibbling about soft clones and have that, frankly, ludicrous explanation of how jump clones work. "Picking the implants out" indeed.
Bah!
But, back to the original topic. I don't play Arnulf as some sort of super soldier. I do play him as someone who takes his meat body health seriously and who exercises regularly as a matter of course. His chosen form of exercise is a martial art. He also usually carries weapons when station regulations permit this. This is not because I want an excuse for him to kill another character, it's because I think of him as a warrior and it's part of his self-image. He doesn't kid himself about lasting more than five minutes tops against an actual ground soldier (DUST bunny or otherwise) however.
That said. Arn doesn't really approve of ship dueling to settle personal disputes (he doesn't like making his crew pay his debts). He would much rather meet up with the other person and go at it hand to hand in some sort of neutral venue. Of course RPing this would have to be preceded by a fair bit of OOC setup.
