Your definition for "badass" is "generic" to say the least.
Also, people are only complaining about Yasuo now, the stuff about the other 2 is like 2 years ago or something, unless you've missed the memo. And no, Yasuo is complained because his kit is innately toxic and badly designed (like a couple others), and naturally generates a lot of hate for anyone on his receiving end even if Yasuo himself is not strictly strong atm. The same can also be said about Riven and Zed's kit in terms of their kit design too, but they are not played nearly as much as they were so most kinda just tolerate them for now.
