I hardly engage with any one piece fans anymore I just read post and from what I've seen, almost every op community is all about powerscaling now
That's easily explainable. The obvious basis is that One Piece, as a shonen, is very heavily reliant on adventure and fighting.
Yes, there are other interesting things to care about in a shonen, even in One Piece, but said things, as expected, progress very slowly, and beyond a few theories here and there, those things don't make for good debates as people simply agree on mostly everything.
Powerscaling is the opposite, each week there's a new thing to powerscale (or make petty claims) about and since there's never a consensus, regardless of the reason, it makes for heated debates. Not to mention new matchups can always be suggested.
It's not bad, though, powerscaling discussions are much more prevalent and actually help keep these places more active and alive even if they can be rather pointless.
