I'll leave my extremely unpopular opinion at the door but..

The fact that Isaac, Shovel Knight, Bomberman, Shadow, Krystal, and Zero are Assist Trophys is way better than most people are making it out to be.
While yes I would have preferred a few of said characters being fighters, the fact that they are in the game as something far greater than a Equipment+ item is a great honor to their characters and to the people who wanted them in. It's not much, but it's a million times better than being a spirit.
