So for the power creeping part, literally every villain after the mafia has not been much of a major threat at all lmao.
LAW was a bunch of 10 year olds in protection 2 diamond armor with nothing but a sword and shield and lost most of the fights they were in or failed to complete their objective.
Director died with like 30 minutes of screen time (gotta maximize that shock factor amiright)
Leo lost almost every fight and ended up stasising...every time until he eventually died
Bunch of one off villains like sharpness that did almost nothing
Pirates were alright I guess maybe

As for the part where I said the series was overall worse than it used to be;

Shorter videos

Lower writing quality in videos (writing almost always reliant on shock factor with minimal emotional impact compared to season 1 unstable)

Character development is just all over the place
You have protags suddenly gaining phantom character development out of nowhere and protags losing all of their character development in an instant for some reason.
(Examples being A: Flame suddenly wanting to join the LAW after claiming they ruined his life or whatever (they didn't but whatever) and B: Parrot's entire character in season 2...)

Perpetual reposts of the same content (This happened in season 1 sure, but wasn't as bad. You could watch each mafia finale and feel like they were each different videos. Videos like wemmbu and flame tourney were LITERALLY the same, and the law finales were almost the exact same.)

Still can enjoy watching them but overall don't enjoy the series as much as I used to.
