I'm fine with Discord. I think Fate is just so no one goes "I win every time always because I'm awesome" while RPing. If you know how to have a character struggle and fail, or respect it if the GM says "That doesn't work" then it isn't needed. I can understand if the GM wants to use Fate for that assurance that no one decides to be an unstoppable mary sue, because at least that way they can't claim the GM is specifically being mean to them if there's a system in play that has objective rules.
