Map Pressure and Objective Control
When your team mates tell you that you are "good for bait" and "just as garbage as the enemy ADC."
Split pushing is a viable option. You will probably die a few times unnecessarily using this method; though to be fair, some map pressure and objective control is better than 5v5 deaths over and over again. One Ace with 3 lanes of double caddies will certainly lose the majority of your turrets and probably Baron; perhaps even the game.
We won the game -- eventually -- with +7 turrets and +2 dragons.
