Then why play video games at all?
I'm sorry, but this laidback approach belongs in Second Life, IMVU, or VRChat. It's giving, "Yeah guys, I'm just here to vibe and chill."
Okay, cool, but I want to get the instance done and be on my way.
Is that toxic? No. While I'm not here to smell the flowers if I'm on a roulette, I can and will be patient enough to help if someone speaks up. People would be happy to give out pointers on how to answer hard mechanics, just like many have stated here in this forum thread. I do not expect perfection as I'm just in there to do my job and get compensated for it (Tomestones, gil, etc.). The only thing I expect for anyone else in my party is to try to do their best in their ability. If your best looks like you messing up here and there in regular content, so long that you're not intentionally griefing/trolling, that's okay. Heck, I mess up, too. I'm not perfect.
However, it becomes a problem when you just give up and not learn the mechanics and your job kit. I am well aware that learning isn't an issue for OP, but if they're repeatedly failing a mechanic, it's most likely not the game's fault. It's likely OP. Whether it's actual internet issues or actual skill issue, you should want to adapt and solve. Seeing this thread existing is somewhat bizarre as it flies in the face of why people play games.
At the end of the day, dumbing things down for a very tiny minority will not help anyone in the long run. Not you, and not the devs, either. To those with disabilities or real-life responsibilities that affect your gameplay, I do feel you, but you shouldn't make it the dev's responsibility to keep catering to you when it comes to difficulty. You need to manage that on your own. No matter when you started, you have jobs at lv 100 now, the training wheels era ended back at lv 50.
While this game does allow for that kind of casual, laidback content, there is a time and a place for them. Dungeons, trials, and raids never were those places. It's a shame that Endwalker pampered you so well to have an opinion like this.
Edit: I do want to pose a question to OP and those in favor: Why are you doing normal mode raids? If you're not preparing yourself for Savage, why go through with it in the first place?
