Now with the memes storming in, might aswell voice my more serious opinion on the matter:
It's real easy to forget that in a game geared towards kids where everyone is more or less anonymous, that there are actual children playing this game alongside with us (persumably) adults. This 'survival of the fittest' saying just doesn't hold any water when you're a grown adult with persumably years of gaming experience beating up groups of new meat, people who aren't just new to splatoon but also to gaming. For the newbie it's such an insurmountable challenge to take on pros directly that they don't learn anything, you learn things by taking challenges that are slightly above your skill level and then go your way up. This way, you approach the subject in a fun, interesting and especially comprehensible fasion and you get better over time.
Going straight from C vs S+ is like tasking someone who never held a pencil in a life to recreate an entire Salvador Dali painting to perfection, it's just not going to work and the only thing that person's going to learn is to drop the pencil and stop drawing forever.
And what if it's an actual newbie who's also an adult in real life? Wow, that might've been you!
