Recently I went back to HXH, and it reminds me of one of the biggest pet peeves I have. Since the dawn of time people probably debated on whether X can beat Y, and while HXH is hardly the Anime that is responsible, it's a representative example of this growing trend where you have completely arbitrary power levels that goes beyond even plot convenience disguised as a deep system. Here, I'm not talking about say if Black Widow didn't die she can probably trade some hits with Thanos before getting tossed aside. I'm talking about series where literally any two people fight each other is about 50/50 no matter how big the difference is because the author himself probably has no idea what the heck is happening, even in the absent of plot bailouts. Obviously if things are to scale then half of the Avengers would've died the moment they run into Thanos in either Endgame or Infinity Wars and that wouldn't be too cool. But nobody seriously thinks that just because everyone gets to fight Thanos that means people are anywhere near his level. At the end you pretty much have only Iron Man and Thor that can even harm him with their own power, Captain America with external help, Doctor Strange and Scarlet Witch can harm him because Thanos is weak against magic (Marvel universe characters are traditionally vulnerable to magic because they don't understand how it works and thus lacks the proper protection against it, despite feats of magic being pretty weak compared to what technology can do), and I guess Captain Marvel can harm him who came out of nowhere.
And despite all that, it's obviously a very improbable victory, one that only happens 1 in 14000605 realities saw by Doctor Strange. Again, this is not factoring in any plot necessity that Thanos has to lose every time or the universe would get destroyed and that'd kind of suck. There should be no question that if Thanos fought any one person or even all of these persons at the same time in a neutral universe he should indeed win about 14000604 out of 14000605 times.
I think it is probably hard to actually keep track of power level and make a convincing fight, whether it's a movie or a book or anything else. Sure, all the Avengers randomly have their moment in the sun against Thanos, but you got to make it look consistent so that people don't wonder why they didn't just overpower Thanos (and even here I think some people ask why couldn't the magic users just overpowered Thanos because they hyped up the magic users too much), so I guess it's easier to say 'well everything is totally 50/50' and pretend fights are decided by like smarts or tactics or something even when you're talking about guys that should win 99.9999% of the time in some hypothetical matchup. It's important to note that despite Avenger have their random technology bailouts for power level issue, it doesn't really work on Thanos because the technology he uses is just as, if not more advanced, than whatever Vibranium tech Avengers have. At best it just prevents the guys from getting one hit killed by Thanos.
Actually, another reason to have bogus power level is that maybe it's actually really hard to do even a good fighting scenes. Gu Long is a master in this, as his novels usually involve hyped up guys that never actually got into a fighting scene, because fighting scene isn't his specialty. But at least he keeps things pretty consistent, like if this guy is supposed to be the strongest guy in the novel, even if he's not sure how to portray that in a convincing manner, he'd tell you this guy just won all these fights instantly or behind the scenes. He won't have his top guy randomly lose to some unimportant guy even though a fairly common theme in his novels is that power is no match for treachery. At least, it's generally someone pretty important who backstab the most powerful guy that never actually fought anyone. I recently went back to watch some Matrix fight scenes, and it's pretty notable that people actually look like they're fighting in a cohesive way with proper team tactics even though the power level in the matchup is usually hugely lopsided (Neo versus anyone, Agent versus anyone not Neo). Compare this to say, the Final Fantasy style of fighting where you need DBZ vision to keep up because everyone moves too fast to be seen by the eye so you just see guys teleport for like 5 minutes and one of them dies. So yeah, I guess people do just suck at coming up with good fighting scenes let alone ones that make sense!
