Are you new to the game? It's hard to take most of your points seriously if you aren't.
Then that makes your complaints even more questionable. We've had several union events and many of those complaints are things that could have been dealt with simply by finding a new union. It's not like you have to interact with people, just find one that has people who log in. The entirety of your complaints revolves around the fact you're in a dead union. If it seriously took you several union events over the span of several months to figure out you can't do this with just a couple people, I don't know what to say.
...Kamihime didn't even start on Nutaku until February 2017. Unless by 2016 you meant that you played on DMM before union events were implemented there.
Ok, ambiguous phrasing on my part there. The window for the complaint to make sense is if you played on DMM in between the end of March (when it launched) and late August (when the first union event ran there) of 2016.
