^ you sir, are mistaken. A support can ward in such a way that the jungler can be seen on the map at any time. This gives your team so much power and options, you should just see it in action to believe it.

If your lane is winning and you have warded sufficiently, you could even opt to go about roaming, trying to help out lanes as if you were a jungler.

And late game, where you will actually accumulate farm, you will grow in strength and become invaluable to your team, just because of your presence.

Support and Jungle might be the most vital and most subtly impacting roles there are, just because they don't HAVE to help in lane to perform their roles well. They just have to disrupt the opponent enough to give the lanes an upper hand.
