The champion you play has little to nothing to do with it. Play champions that align with your play style and play with a gold control mentality - not a KDA mentality. 1 kill = ~15 creeps = 1/5 of Nashor = 1/3 of Dragon = 2/5 of a tower. Keep that in mind and, most importantly, play for fun. Your score goes up the most whe you're playing to enjoy it rather than playing to win.
