Will reply to PK's post separately; don't want to derail the conversation.
My advice: dial back a bit. When Joker came out, you eagerly and emphatically shouted that he couldn't ever be anything higher than low tier. Within less than 24 hours, you said that you had come around but would never see him as anything higher than mid tier. The next day, you said that he was probably high tier and that you were going to main him. What strikes me about this isn't that you changed your mind--intelligent people do change their mind in the face of solid evidence. What's striking is how convinced you were that you were right at every turn.
Your conviction leaves a bad impression on the folks in this thread--especially since you have no corroborating evidence for some of your claims. If you can't post with more evidence, then posting with less conviction would solve the problem too. For example, consider asking others for their opinion instead of offering your own, and then talking about specific points:
"What parts of Olimar's kit seem overtuned to you?"
"His up-smash is broken, why can he spam it safely?"
"To get a really broken up-smash, he has to have Purple Pikmin. Purples are definitely overtuned, but it's by design. They're meant to encourage you to approach Olimar just like the threat of Cloud's Limit charge is meant to make you approach Cloud in neutral. If you put enough pressure on Olimar then he'll only have one Purple out at best, and you can prepare for the up-smash when it's on deck."
This is useful discourse.
You could also talk about things that people could do against Olimar that they're not doing right now, like abusing his bad roll (we all saw Ally's Snake tear through Olimars at Pound by abusing that roll).
You're not doing any of that. Right now it seems like you're just here in this thread to shout your opinion, instead of to teach, learn, and engage.
