Have you ever noticed how Hunterchads create funny, clever and thought-out OC while OPfags seem to always post the same pictures and the same shitposts? How many times have you seen OPfags repeat "BTFO", "hiatuspic" or "rent-free", or how they always say they won when they never provide a single insightful post?
The reason for this is pretty simple. HxH is a series that wants its readers to use critical thinking, where characters analyze situations in depth but also more abstract concepts, where they are conflicted and think about ethical or logical implications of their actions or those of others. Wan Piss on the other hand, is centered around a cast of one-dimensional characters defined by simple gimmicks, and in return you never get any thought-provoking dialogue. It's all very manichaean, the bad guys are evil oppressors (who also have a cookie cutter, "tragic" melodrama-tier backstory) and when it attempts to tackle serious themes, it does it in such a shallow and predictable way it's not even worth mentioning. It's all very repetitive, it constantly follows the same formula, much like OPtard posts.
This is also the reason they just don't know how to be funny. The humor in Wan Piss is aimed at little children (Luffy loves food and is dumb, isn't that hilarious? Look at Sanji bleeding out of his nose from seeing another Nami clone! That's only the 8th time in this arc!), and as a result, you get all these cringy OPkids shitposting in HxH threads out of butthurt like >>178506928
The only feeling OPtards should evoke is contempt. They actually are lesser beings.
