Support Rumble
I've tried it twice now and the first game was against a Kat/Cait lane with Sivir as my adc which we won by a landslide. Rumbles E is great at harassing while your adc farms because even at level 1 you can do large enough damage to force them to back or risk death. Game 2 was against a Thresh/Kalista lane. With Kalista or any other high mobility champion it is harder to harass, but we were still able to crush our lane.
I just want to know what people think about Rumble as a support, and before you start flaming saying just play a real support. In normals and even low elo ranked games you should never try to be too serious and have fun playing.
