There's a lot of stuff that you don't like which I personally didn't mind, so I can't say I can agree with you on a lot of the complaints that you have.
Asura was completely out of nowhere, whereas at least Zoro's power-up in Onigashima had some explanation and basis to it. Luffy was more than a nuisance for Kaido pre-1010; one Red Roc had him hallucinating, Kong Gatling put him on the ground for a short while and he actually made the effort to start dodging Luffy's attacks in 1009. Even after unlocking advanced CoC, Luffy was still beaten again before he returned with Momo, so not quite toe-to-toe with a Yonko right off the bat.
The fights in Enies Lobby were well-contained or whatever, but they lacked the tension or seriousness they should've had (imo) given what was at stake with Robin's rescue. The Straw Hats have struggled more in Wano than in Enies Lobby, with stuff like Nami and Usopp outright losing and almost dying, Luffy getting thrown into the ocean, Zoro getting put in a pack for 10 chapters straight etc, and that I prefer over Zoro getting annoyed by a goofy giraffe or the fanservice/stupid forms showed by Kalifa in Nami's fight for instance. Touching on Sanji getting trapped, it was to show his progress after WCI as a character (learning to rely on others) and to give Robin some of the validation that she had always wanted before meeting the Straw Hats. Personally don't really care about what led up to it.
Additionally, couldn't you also say that the fights in Wano are leading to the overall success of the raid, like how the fights in Enies Lobby led to Robin's rescue? CP0 even comment on this matter in Chapter 1003, that the officers needed to be defeated or they could take out hundreds of samurai each.
I don't think people actually thought that Zeus or Kanjuro would die (the first time round), Ashura Doji's status is not confirmed and why even bring up Luffy? He's been in near-death scenarios so many times but we know he won't actually die since he's the MC. Yeah I really dislike the other fake-out deaths in Wano and I think they're just as bad as the Franky Family/Galley-La fakeout deaths in Enies Lobby, given how the latter deaths were presented and the crew's reaction to what happened.
I keep hearing complaints about Big Mom's amnesia but I didn't actually care too much that it happened despite it being a plot device, so I'll just leave it as a case of personal preference. Same goes for Mother Mode and the Tama plot, because it seemed like Oda was interested in exploring more of BM's character and perhaps showing how unstable the alliance with Kaido was on some level. I will agree on Yamato's inclusion being forced though, and maybe she should've been the one to help out in Udon instead to introduce her earlier in the arc and build her up more naturally. I can also agree with the mishandling of the Numbers, Mimawarigumi, Jack and Perospero.
What do you mean by "Camp I-wanna-go-train", is this Udon you're talking about? How would you have felt if Luffy did no training at all before the raid and reached Yonko-level anyway? He started using advanced CoC because he realized Kaido was using the exact same technique that Luffy had been training to use in Udon, except with CoC instead of CoA.
Anyway, I've personally enjoyed Wano overall till now and it's okay if you don't like the arc, they're opinions at the end of the day. As an example, a lot of people hate Fishman Island but I thought it was a fairly good arc overall that did a decent job of setting up future plot lines for the rest of the story, as well as showing the Straw Hats' growth.
