The slight differences between boffer LARP fighting mechanics can generate all kinds of fun. My wife and I first met while LARPing, in a system whose fighting mechanics were derived from SCA rules. Every hit was potentially deadly, so footwork, parrying and dodging were vital skills. We tried out another, hit point/Nero derived system, where defense was all but ignored- the limit of tactics was to stand in and swing, hoping the enemy dropped before you did ("Seven magic! Seven magic!"). At the beginning of the weekend, some of the younger player made disparaging commentary to my wife, who is quite petite and frail-looking was playing a single-sword pure fighter (no florentine, no magic). They didn't know she had been fighting with that style for about ten years, and playing piano gives excellent wrist strength and control with a light boffer sword.
End result- at the end of the weekend, there was a nice long conversation about who had died and how many times. Most of them averaged about three, with some having died as many as six times (though no final deaths). When they finally got around to asking, my wife and i both had the same answer- "no deaths". The shocked looks were, sad to say, probably about the best part of that particular LARP- far too much PvP and resource item management for me...
