What role/champ to play?

Okay so I have a bit of a dilemma. I don't know what role/champion to play. Here is what I think about all the roles and my personal playstyle.

(This is my opinion) Top- Too boring, either you need or they feed you. Plus, you do not help the team much. Jungle- Too passive. I always get yelled at for not ganking and I am always behind than the other players, I feel useless. Mid- Too overused. I feel as if people only play mid nowadays. I enjoy the role but I always get ganked and in dynamic que I almost never get the role. ADC- I enjoy the role, but I always feed, my support isn't the best and I don't really know how to play the role. Support- It's fun, but the only champ I enjoy is thresh and I dont like the fact that I cannot deal much damage and I need someone to be near me to do anything. I want to be able to make more plays.

My play style: I like getting kills, and have high bursty attack speed (I really like Kog'Maw, Jinx and Caitlyn) being able to run into a fight and grabbing 2-3 kills but I also like playing a bit more "troll" champions like leblanc.

So, what role should I play? And what champions do I play? I keep getting stomped in solo que and I cannot find a champion that I can play and just carry a game.
