Guess what, Tryndamere can teamfight too, he is a monster in teamfights if he gets even slightly ahead (which isn't hard in the slightest) unless the enemy team has a shit ton of hard CC (which Yasuo is countered by too btw). He can also assassinate people which is why dealing with a splitpushing Tryndamere is a pain the ass since he will just kill the person you send after him, but if you send more his team will slaughter the rest of your team elsewhere while Tryndamere Es over a wall, waits 20 seconds for you to leave and then goes to split the same lane again, or just TPs to the other side lane. It's not easy to deal with in the slightest.
ANYONE can teamfight. It's not something he's strong at. He needs to be ahead to do it well and he basically serves as a clean-up guy. If he jumps in first he's CC'ed and killed. He can't engage, peel, or reliably reach the back line unless his teammates set him up VERY well or the enemy team is dense as hell and lets him flank the adc or something. Yes he CAN do it, but it's situational. No one picks Trynd saying "Yeah. I'll go Trynd for his sweet teamfighting!".
Also you and I have a vasty different definition of "assassin". I guess yours is "anyone with a mobility skill who can kill someone". That's.... fair, I guess. But I wouldn't call him an assassin because he's not built around playing like an assassin. Sure he can kill you 1v1 if you come to mess with him. That is what I call a duelist. They're pretty similar, I suppose. He lacks the kind of tricks that other assassins have. People like Zed, Kha'zix or the like. He doesn't dart in, kill a carry and dart out. He spins in and starts chopping like an lunatic. Ahead he's pretty bursty, yeah... but his damage is mostly SUSTAINED damage, not burst like an assassin. Still... splitting hairs I guess.
Catch Yasuo splitpushing with your team? He is dead, he has no minions to run away from, all you need to do is hit 1 CC spell, 1 of the many CC spells that aren't projectiles that a majority of the junglers have, and he is a free kill.
So just like you can kill Yasuo in lane if you use your brain, and boom same situation. Not only is Yasuo useless because if you are top you will massively outduel him or if you are mid you are gonna burst him the second his windwall enters CD, he can't splitpush as good as other splitpushers since he has no escapes
Ok, here is where you lost me. First of all... if it takes your team to stop the splitpusher... he's doing his job. That is the point of splitpushers. NONE of them are invincible. If four people rush top and catch trynd, he's dead. Singed? Dead. What matters is that it took four people to stop him, and while you're doing that the splitpusher's team took towers, dragon and the like. Yasuo works as a splitpusher (at least in low-medium elo) because he's a powerful 1v1 duelist and he scales really hard. If you go for him alone he'll probably kill you, and if you bring your team, his team will get crap across the map. You won't even set him back too hard with the death either, since the gold he'll make from Csing alone is so strong on him due to his bananas scaling off of crit items.
And FYI, I can stomp all over Trynd in lane too. In fact, it's easier. Trynd pretty much has ONE trick. He right clicks things. He's absurdly easy to harass, zone, out-trade and generally give a bad time to in lane. He's pretty easy to kill too if you're savvy. 90% of the time games against Trynd have the Trynd getting slapped around in lane, then they stay in top and mindlessly push top all game because they're behind and can't teamfight but the constant pressure they put on the lane is annoying and hard to deal with. This is EXACTLY what I was saying, so I don't know why you're so pissy and disagreeing with me here. I'm not even sure what you're disagreeing ABOUT or what your point is? That Yas is a worse splitpusher than Trynd? Um... that's true. I don't think I ever said he wasn't, but sure. That Yas is a worse champion than Trynd? They're both absurdly annoying with frequently obnoxious, BM-prone players and awful toxic playstyles that I think ruin the game. I'm gonna give the points to utility tho and say Yas is more obnoxious at more things due to his overloaded kit.
I actually very rarely see a Yasuo aside from me, and even when I do, that Yasuo is complete and utter garbage(also like me). Vayne, Rengar, Lee Sin, all those champions are way more popular than Yasuo atm, so if Yasuo is hated because he is popular, than that's a huge double standard right there.
Vayne, Rengar and Less sin are ALSO often the targets of rage, bile and hate... for the record. All of them, save Vayne, are resourceless AD killbots that have very strong or frustrating kits. Lee has a TON of mobility, utility and damage, and Rengar cheese-kills you if you're not hugging tower when he arrives in your lane. FYI, you won't know he's near your lane until it's too late. All three of those champs are also superb duelists, able to kill people brutally in 1v1's, and this is why they get a lot of hate.
And lastly, I don't know where this magical place is that you never see Yasuo... but for me he's usually permabanned because no one wants to deal with his obnoxious ass on either team. The few times he's NOT banned... someone will often pick him. The dude isn't overpowered, just overloaded... and really, REALLY obnoxious.
