That's how feedback has always been. Development pipelines are long and span years. They've not even released Dawntrail yet and they're already in early stages of working on 8.0. It was same way before. Any feedback that was given during Endwalker won't be implemented until 8.0 and feedback during Dawntrail will likely wait until 9.0. The development process is always way ahead of what people actually receive, and they're not going to scrap things theyre already working on right now to respond to feedback in the middle of process, they'll just slot it in for when they start working on new expansion from scratch again, while keeping the work on current next one going as is
