Every time I see a player on my team who intends to pick Yasuo I always make sure to ban him. I have never, ever had the good fortune of having a Yasuo who does not give up first blood and end the game something like 1/9. I'm convinced good windy man of much Japanese players don't exist. Especially if they're a Yasuo top player, depriving our team of an important tank like Malphite.
Vayne, if i support
this is funny actually i read the tittle and thought ''yasuo'' I'm sorry yasuo players but in my time in ranked this season i have seen 1 great yasuo every other one has sucked.
if someone had highlighted him though i wouldn't ban him, id rather have someone on someone they want to play and do well on, it will just detriment the team if you start banning peoples picks.
Can I just say, that's a dick move, and I think most people would be inclined to troll you if they knew you banned their intended on purpose.
and you also might be banning good yasuo's from your team, e.g people like me wth 60%+ win rates with him
You do realise that every role can have a tank in it, right?
Adc 
Mid 
Jungle has at least 50% of the champs as tanky
Support has 30%
So you have plenty of ways to get a tank, but of course TOP is the only place tanks can come from. Just like only supports can ward!
this is the type of people who later cry about 'trolls' and 'elo hell'.
Man that would tilt me so hard if you did that to me. I once had a teammate last month who banned my Volibear because "He's unviable in the jungle, you fucking scrub!"

Yeah. One of the top 5 junglers in the game is "unviable" in the jungle. What...
I got tilted so hard I picked Urgot jungle. We still won though.
Lol I used to ban garens way back due to his selfish nature. Got tired of walking KS machines that only pushed top lane and ignored the rest of the team.
You may not like him but when you do that people tend to troll
if you did that to me and i was mid i'd instantly lock into 
and build full support mid
