Newer champions just don't feel right

Here "recently" we've had

And a lot of them don't even feel that good to me.

: Pretty good if she can get in the right spots at the right time. : God-tier ADC. No complaints. : I just feel like this guy doesn't do damage, or really, the type of damage he needs. I don't like the idea of making a mage that does sustained damage. : She was bad, then buffed, then got in the spotlight, then got nerfed into the ground. : This champion just feels like a living meme. I think he can be good into certain matchups, but he's too open to ganks, and has to build damage. : The champion feels hit or miss. I feel like he's good for someone that plays Nunu or something. The champion isn't good when him or his team get behind. : She's still really new, so it's hard to say. She seems similar to Irelia, Riven, and Fiora.
