What if support would be more popular as roaming menace instead of the marksmen's bitch?

The current state of playing support could honestly be described with one single word much of the time: degrading

Not in playing a position that is by all means required to make a team function but in that you are often left to try and focus assistance on one specific ally regardless of if they are good, bad, or chewing you out for not warding the right place at the right time. You are expected to stick with them.

What if supports were not only able to help mid or top fairly often but were expected too? What if the the baby sitting the marksmen mentality of the game is keeping this position form being more enjoyable?

Yes I bring this up somewhat as a response to the support singed situation. Support should be about getting advantages for the TEAM not about protecting a risky investment. And yes Marksmen are a risky investment.

Why does the marksmen's bitch station exist? This is largely tied to 2 things: exp is boosted when shared and which classes tend to scale best with gold vs Levels.

You guessed it. Marksmen are often considered to scale better with gold for items then levels when compared to assassins, fighters, mages or tanks. Since marksmen are often seen as the class least dependent on levels and most easily able to scale with items having them split exp with supports is a huge part of why it came be the meta it is today.

What could be done about this? Removed the Exp boost when exp is being shared. This will not force supports to have to leave the side of the marksmen but it would make them best off not sticking around one single ally all the time. Many other MOBA do not have EXP boosted when shared.

Then make a system where all allies who are higher a higher level will passively grant 1 exp a second for the number of levels nearby allies have over you. Not an over the top boost early to mid game but it will add up especially later.

Example of how this would work is: Level 9 support is near a level 12 mid and level 13 top will result in the support getting 7 exp a second.

Just my thoughts on the situation and part of the reason why not much of the player base likes to play support. Being dictated in what you are expected to be doing even when you could easily be so much more of a game changer if you were not expected to baby sit one player would make the position more enjoyable.
