@Meddler, how about an objective buff meant for supports?
Meddler, I was just wondering if it'd be possible for riot to add some kind of objective that gives a buff that would mainly interest supports? Maybe it could give the support that gets it some kind of relevant bonus like bonus heal and shield power, boosts active cool down, buffs ward vision or trinket CD, etc...
Since supports are supposed to be the most team-oriented member along with the jungler, maybe it'd be good to give them an objective to fight over. Perhaps something where they leave lane with the jungler to get something in the river.
As for placement, maybe make it a little critter that runs away just before the dragon spawns or respawns. Teams that get to the dragon early will have something to do and have a little reward for securing the area early.
