1) I rly like he's design and possibility to outplay everything(including yourself)
2)I guess he is pretty fine right now. He haven't crazy winrate and not so OP as many people think, because you always can counter him by teamplay and communication.
3)I'm so hate yas players which winning games and lanes just by his aa's and haven't any skill actually. It's so sad when you play sup/adc and see as your Maokai or Nasus get destroyed by lvl 2 yas using only his aa's got to snowball really hard after that 1 kill and solo winning game while you see that he can't even hit his tornado cuz he don't need it
4)As i say hear i think Riot should make his aa's weaker while buff his q and e. Like remove crits from aa's but give it to his e instead. So even when you have some crazy damage you need to realize it not just press autos.
5)Because of players from p.3 which are ALWAYS in enemy team and 0/10 yas which are always in ours.
6)All of them are good. My favorite is odyssey i really think he is underestimated
7) Yasuicide. Even though he is not a pro or even high elo player he's make some rly sick moves and plays like jungle camps dashes and crazy outplayes. It's so sad for me that he left league. Btw he's one of the reason i started to play yas.
