How to make supports more appealing
By removing sightstone 
Does anyone remember the cancerous warding sessions in season 1 2 and 3? Warding isn't satisfying, especially when you have to pretty much ward the entire map all the time back in season 3 and below. I'm glad there's a limit to place wards on the map, because it's boring to do that. In addition, trinkets exist in this game to encourage your teammates to ward. It's more satisfying to heal someone, shield someone and making the plays. Sightstone just holds supports back as an appealing role. Eventhough this will still make the support role the least desired role, at least it's one step closer to make supports great again
