An Idea to help lower the level gap between the support player and his/her teammates
I was the thinking bring back the season 4 mastery Inspiration: Grants 10 / 20 experience for every 10 seconds while near an allied champion with a higher level
Make it as a unique passive in the gold income items
You can also make the experience that you get for ever 10 seconds scale with time. In the beginning of the game its 10 which then scales to 100 if the game gets to 50 min mark. Or just leave it at a fix number like 20.
then you can use your trinket slot for either pinks or place the
where as all other roles still have their trinkets
