As a ZSS and Corrin main, K Rool is mostly an easy win for me. Juggling him and punishing his crown spam is so satisfying. So I don't mind him at all. But yeah, projectile spam is more annoying than ever. I do groan a little bit, if I have to play for the 100th time a Samus, Link, Dedede , Belmont or Snake, all basically using the same strategy. I can do fairly well against them, but sometimes even when I see a Boomerang, Gordo or Bomb coming I still tend to get hit by it. Lag messes up my timing, it gets even worse when I buffered an airdodge, because I pressed the shield button too late and fall to my demise like an Idiot. It's annoying but well, at least I get a good laugh of it when that happens.
Of course, everyone can play the way they like, but it is kinda sad, that quickplay mostly consists of heavies or zoners. I mean, the game has 70 characters after all. Characters that nobody uses like Rosalina, Duck Hunt and Greninja need some love too, you know.
