LARPing is the main reason I stayed far away from VTM in the 90s. Running around the city at night wearing sketchy costumes was not my idea of fun, and the fact many of the players were also in the BDSM community meant sometimes lines were blurred. Also the idea of boffers just killed immersion, not to mention I was taking Chinese sword fighting at the time, so I saw little point in engaging in Nerf combat.
Those of us in NERO (boffer LARP) didn't look too kindly at VtM LARPs either. Basically a bunch of posers who play rock, paper and scissors. . Not like us boffer larpers who will slog through the mud, rain, and snow with 30 pounds of gear on to get to the adventure wondering whether that barbarian player we picked up back at town is really there to backstab us.
There are different types of LARPS and different LARP Organizations. The one I was involved with was in essence D&D in the woods with a Player vs. Player component mixed in. i.e. it was possible to get away with killing another player characters. The my picture on this site is me dressed as my Endless Star character.
The advantage and problem with boffer LARPS is the live action. It an advantage because it very immersive, it is a problem because there are many standard fantasy tropes that are difficult for us to do. Not the least of which is the fact that staff needs to eat, sleep, and shit. And it take time to get from one side of the site to the other.
