"I either would prefer a large amount of CC or some sort of heal. Both would be even better.

I would love to be able to deny farm.

I prefer having an ability that could be game changing. "

These all scream Nami to me. Nami zones relatively well with the threat from bubbles and W/E poke, has a gamechanging ability in her R (hell, even a well-aimed Q can swing a teamfight if enemies are bunched up enough) and she even has the heal you want. Beyond that, my recommendation would be Zyra for similar reasons - high zoning ability with her plants and a gamechanging ultimate - one well-placed Zyra ult will win teamfights for you. No heal, though, but that's a relatively rare thing in League generally.
