Support as a role will always be this way. The game would be better if it didn't exist to be honest.
I would never play it if certain champs werent made to only be viable in that role.
There is no reason to want to play a gold starved under leveled champion that will basically not scale into anything better than it was at level 6.
It's gotten a little better. But when one role has to make sacrifices for the team when no other lanes do then it is going to be underplayed.
Anytime supports are strong enough people might want to play them they get nerfed very promptly.
