Just because you are/have a Caitlyn/Nidalee doesn't mean you shouldn't buy wards.

They don't cut it. If someone stumbles on top of them, they'll pop, sure, but they will not reveal what's going on beyond their tiny corner of the world.

Also, when you feed because of enemy jungler ganks and I (your own jungler) can't get close due to the enemy team actually warding, it's your fault. If you attempt to counterward, I'll be back down... maybe, if you don't have a 10/0 Vayne from feeding. In which case your lane is best abandoned.
