Remove smite from the game if you want to make dragons a team objective.
And especially take power away from junglers. Jungle may be a terribly weak role right now in terms of carrying power but it's the most influential role on the map and it's pathetic to have junglers who would rather farm on the other side of the map while the team desperately tries to contest the dragon.
Junglers have way too many tools to influence the map and something needs to go. I'm not going to argue about the exp buffs because it falls on deaf ears but something from the jungler's kits need to go in order to reduce the negative impact autofilled/bad junglers have on the game.
After this post goes live a million souls of junglers will cry out in fear and i don't care. A bad jungler can singlehandedly ruin the game harder than any other role and there isn't a reason for why anybody other the jungler should get punished for not contesting objectives which they have the largest agency on.
