>>40216169I said this before: the key to making a productive and memorable gen is camaraderie and synergy. No matter how much you like the person on the other side of the screen, you can't build either without meeting in person and JP/ID meet face to face all the time.
Meanwhile, EN is a global branch, even the American Holos are far away from each other. There's simply no chance for EN to bond besides meet up like this and you clearly see the results when they do.
