That checks out. I don’t know what it is about Vampire that attracts such toxic people, but it does. Particularly within the LARP space; I’ve had better experiences with tabletop WoD community, though the problems do still exist there to a lesser extent,
(Warning, details require knowledge of VtM): I think it had more to do with the fact that I personally resolved several storylines far quicker than desired. I was playing a Tremere for about a year, slowly amassing a library of rituals. It got to the point that no one really knew what I could do, and when I'd become the Prince of the city and was attacked by an NPC Assamite that was intended to escape (thus leading into a wider investigation), I obliterated them outright, and the Storyteller in charge quit on the spot. I wasn't aware of what the storyline was about, just that someone was trying to kill my character and I reacted...less than favorably to that, going all out.
For months, my coterie expressed their fears that I was a helpless cream puff and trained me in combat skills, and were quick to defend me when attacked. I think it surprised everyone that I was actually dangerous (apparently when I'd shared my concerns, they just laughed it off- surely I was no threat to a Brujah or a Gangrel in combat!).
(The house rules of the game used concepts from Blood Magic: Secrets of Thaumaturgy, one of which was that to target a spell, you needed to have some connection to the target, such as physical contact, something that belongs to them, knowledge of their True Name, etc. etc., and once you had that, range was no longer an issue. So during the fight I used Theft of Vitae to drain away the assassin's blood, and then once I had that, I was allowed to use another power on the target even though he'd escaped using his Obfuscate Discipline. Said power allowed me to boil the blood inside the target, which also inflicted aggravated damage to them. I got a lot of successes, which nobody expected, as it was a difficulty 8 Willpower roll. But in a previous storyline, I was awarded a truly busted Merit that I didn't often use because it was really silly, and I had bonus dice due to my Enchanted Talisman...tldr, Final Death to my attacker).
