lol, no. Ori is fine, they didn't even need to nerf her AA damage like they did a few patches ago. Her damage is relatively low and is mostly dependent on the items she builds (scaling). Her damage requires positional awareness and an understanding of her ball and everyone around her's speed and skills. That ball can take up to 2 seconds to travel from one end of her range to the other. You need to predict where people are going to make that move. Also since her ball is so slow you can avoid it with tier 2 boots, and if you need more speed get the alacrity enchantment.
If you are complaining about her ult..well cut that shit out. You know there is an ori on the other team, you guys should literally never be grouped in a way that'd allow her to get more than 2 people. "Oh but Lee sin brought the ball to us." So? were you grouped? Did he come out of the jungle that you didn't have warded?
Also 8-11? Of course she will have damage, she has 8 kills and was probably farmed. Her number of deaths has nothing to do with how much money she will have. If you are dying you should be getting your gold from farm, but hey you guys died to her even tho she was behind and had more deaths...i think that says something about your team more so than her.
She isn't Kat, fizz, yi or yauso who can go form 1-10 to getting a penta kill. She is just a girl with a very slow moving ball.
