This. This is the main reason why. The devs rarely ever show off the new girls officially on twitter, at most you're only getting a name or a small teaser. They did do it recently with Usugumo, but it basically never normally happens. I can't think of many other games that do this, it's quite strange.
I guess that's all I'm gonna say. The original statement of George Washington being an Avenger with a shield was supposed to be a joke, but of course when it comes to Nasuverse, jokes or not, people will just want to attach paragraphs to it for no reason.
Or generally. Cause some people can't tell when a joke's a joke from my experience.
