I’ve been playing with nothing but players of my very mediocre and average skill level all night then out of nowhere matchmaking breaks and I got put against players that could do 30+ kills on their own in a match? What is up with that. Is there SBMM in social or is it totally freaking broken? I was having a lot of fun tonight until the clock started to run out on my XP boost and I just needed to win one last Team Slayer match but then I got completely wrecked by someone who clearly outclassed all 7 other players in the game and should have just been playing Ranked because I don’t see how they had any fun carrying and crushing a bunch of slumps. Needless to say it was annoying to me. Challenges are fun because they’re the only thing that keeps me playing when my (especially when my friends only want to grind Ranked or practice Ranked in customs 
) but their implementation is annoying.
Edit: Skill based matchmaking is in fact NOT Super Smash Bros. Melee
