Shitty bait OP aside I've always thought it would be interesting if you could compose a party for battling out of any three characters that you've recruited. It wouldn't really work in deltarune the way it is now, since Kris' acting is integral and it's too story focused for having any possible party to really work, but I've always thought with all the different characters that each have their own stats and elements that something like this would happen, either in a replay segment or a future chapter.
