I literally NEVER see qq threads about her, and her win rate is nothing special either. Compared to other mid laners in this game her burst isn't that good either, and unlike other burst abilities you can actually dodge all of her damage, and her mana costs are REALLY high. She has tons of counterplay, high mana costs and cooldowns, and she doesn't have good burst. She is literally the healthiest mid in this game. No reason to nerf her at all.
Muxxik15 votesHonestly I'd much rather be dumpstered by a really good Orianna player than half these assassins being played right now. Orianna is a lot more fun to play, and a lot more fun to lane against. Winning is rewarding, getting a good ult or a good save with e is rewarding, and getting wrecked by Ori doesn't make you want to quit.
RavenMagus5 votesI personally don't find Orianna very fun to play against. I found her to be one of the most cancerous mages to play against for years and years. She has easy poke, she does insane amounts of damage with insane amounts of utility, and is also very hard to kill at the same time. She doesn't seem as overbearing right this second as all the instant death assassins, but I don't mind her getting nerfed as mages will be relevant again someday.

Pro play.
Of course. I completely forgot worlds is coming up, and we can't let any champ with a shield be viable.
LTK KoRo3 votesNo? Before the nerfs she was played often in pro, and after the nerfs, she's still played. Orianna fully deserved this nerf, and she's still in a good spot. And she isn't the healthiest mid by any means.
HP Crookshanks5 votesAgreed. She didn't need nerfs. She's nerfed because they wanted more flashy plays for pro play.
rtbf761092713 votesit's time for them to nerf some of the most long standing pro play picks again. They need their shiny new overloaded champions to be picked in worlds 
Blåbæret3 votesNerfed because of pro play.
Gotta love how they dumpster champions thanks to the snorefest that is LC$.
Fisher No Chains3 votes“High mana costs and cooldowns” Are we talking about the same champion?
That nerf was fair. Orianna has a shield and so she doesn’t really need 42MR at lv 1/2/3.
