Support Nidalee is their way of saying, "I don't really want to play support."
You're kidding me. A decent nid support is straight her heals are ok and them spears/wards used right hurt. I've had quite a few feed my vayne like that.
Though nothing like that taric!
Support is support if you understand the role and use the right person you can do anything to the current meta. Had a TF yesterday be my support and we wrecked a Graves/Soraka combo even with them having a jungler constantly help them out.
