I know; that's why I'm willing to not question a few things, like the petal storm, but I feel that giving the final boss a shotgun, making it lower our collective accuracy, having one of them seemingly protect the others from the few attacks that go through and giving another one the ability to just hit whoever hits them might be a little too much, especially when it has been proven that any one of us dies at the drop of a hat, or gets stuck on the ground, or has an uncanny ability to attract teammate attacks. The default system to roll our moves might be already compensating for our numerical advantage, and that's something to repair, or compensate.
