To everyone saying, "omg dis wut u get!" If you really thought 1.0.7 Diddy was that bad and you just could not beat him, then don't be upset if people, idk, accuse you of not being good at Smash. He was not the best character in 1.0.7 and if this is what Diddy mains get for beating you, fine. The same Diddy mains will still beat you with double nerfed Diddy.
It's really not the worst nerf and I don't think it drops Diddy to mid tier or anything... Definitely still top 15. I kept putting off playing him when I heard about the patch because I thought it would make me mad, but it's not so bad. He still feels really comfortable to play as, but setups will require different moves now.
