if support/jungle didnt exist the game would be insanely boring.
Legit just remove support role from solo q ranked or make it so supports actually get a punishment for roaming.
Switch from any lane, take any champ, go support and run around the map and usually win the game because the average support player is a zombified human and cannot possibly fathom matching a roam. And it's not like they will pressure the 2v1 or dive bot either as a response.
The immense earth shaking responsibility of trying to match enemy support is obviously too much of an ask for them (even though they are not having to farm either) given their fragile condition. Their nervous virgin hands start quivering at the thought of having to take any initiative on anything and they fold like origami.
Supports are simply too bad relative to their counterparts to be tasked with managing the possible roam options.. Completely exploitable role because the playerpool is so stunted.
