Some of the points that you've raised are fair and reasonable, and I agree that there are a lot of agenda based criticisms or just empty/tired tantrums.
A lot of Zoro fans saying Luffy should be dead him surviving is an ass pull and plot armor.
For one this is literally the dumbest stance that you can take when reading a Shonen manga. Oda isn’t going to kill is main and most popular character in a series that’s been running for over 20 years. If he does kill Luffy it won’t be until he’s accomplished his goals, that’s just common sense. How is Luffy surviving an ass pull? Kaido thinks he’s dead he literally just announced it. The last defeat he threw Luffy in the sea which typically should be death for a devil fruit user. But let’s talk about Zoro and times he should have been dead. The nothing happened moment was great but Zoro should have died even Kuma mentioned it. He should have died from Mihawks slashes Arlorng mentioned it in Arlong park. He should be dead now but he’s not he’s more than likely about to get a black blade with the reaper situation going on. You know why plot armor. Zoro has just as much as Luffy.
Clearly he can't die, but it also depends on how an author realizes it. Because if we look at Oda's writing in Luffy's case we are compelled to say that it was absolutely lazy and tired.
Luffy was literally drowning in the deep sea, but coincidentally he was lucky enough to have Law's crewmates there to save him.
All the example related to Zoro that you've posted are totally a different situation since that he didn't survive by sheer luck like Luffy. He survived because he was strong enough, both physically and mentally, to endure all the pain he took.
I hear a ton of complaints about Luffys power ups being ass pulls.
How Sway? For he trained for ACoA and in the process learned to flow his haki. Then he saw Kaido flow ACoC into his attacks and was able to mimic that because he specializes in CoC and just trained to get better at flowing his haki. Awakening is more than likely what’s happening now how is it an ass pull when we have never seen how fruits awaken and he has had his fruit for over half of his life? You don’t even have anything to compare it to in order to call it an ass pull. Law awakened his fruit between Dressrosa and Wano and Law didn’t do shit during that time. Don’t tell me he had awakening in Dresrossa if he did he needed it against Doffy. Let’s talk about Zoro he literally skipped CoC and strayed using ACoC out of no where. He has never consciously used CoC in the series but he just learns the advanced version mid fight? We can talk about ass pulls. How about Enma the only sword that we’ve seen in the series have an affect that forces the wielder to use more haki. That’s not an ass pull though? It’s hypocrisy at its finest. The fact is Enma forced Zoro to exert more haki than what he had causing him to learn how to use conquerors I get it but it makes a lot less sense than Luffy getting ACoC.
Here I somehow agree with you because I think that it was not an asspull Luffy learning Adv CoC, but I still have a big criticism on how Oda has written the situation because for the second arc in a row he let Luffy copy the ability of his opponent and that's kind of repetitive.
Not to mention that I am not a big fan of the "copy by watching it once" shonen trope.
It's much better if an author explains a powerup through emotional distress/rage/whatever make a character snap all of a sudden.
Now Zoro fans are saying Luffy is becoming Joyboy and it’s not his own haki that he’s using.
It’s no way that Luffy is going to turn into another character, he’s going to be a more powerful version of himself. He’s not using Joy boys haki. Zoro fans hated when people said Zoro was using Odens haki which was also bullshit.
This is what I was referring to when before I said that some of the criticism was only "empty tantrums". That's just for joking.
Obviously I don't think that Luffy is using JB's Haki, but honestly after all the mockeries that Zoro and his fans had to undergo can you really blame us?
It's not a point to be taken too much seriously
Luffys fruit changing doesn’t make sense.
How doesn’t it? The government hid the name for a reason and we don’t know what it does yet so how can it already not make sense?
This one is a serious matter though.
There are several issues with this that can potentially lead to plot holes, if they've not already did. Like why in the world the WG snapped only now?
Besides, let's say that it's fully confirmed that Joy Boy had the same DF of Luffy.
I don't know about everybody else, but to me this is a fanfic scenario literally.
But sadly enough Oda already went with this route in the Sabo-Ace and Foco Foco case, and like we say here in Italy:
"To make mistake is human, but to persist it is diabolical!"
