So, I had 2 ideas:
First, what if the members of B team are equally as strong as the members of A team (or just about) but the reason they're weaker is that they don't have very good teamwork? It would allow for the members of team B to have a considerable amount of character development as they get to know each other better instead of already knowing each other, and it would also make sense since in most situations even a team of weaker individuals can still overcome a powerful enemy if they have strong teamwork.
Second, when you upload them to youtube or wherever, will you put subtitles on it for that subtitle button that youtube has?
