Gaming career insight.

I like to design concepts, I love working through seemingly unsolvable problems to make something more efficient or superb. I have written what seems like books of game concepts and ideas for features or whatever have you. I'm about to go to college for conceptual design and my dream is to one day own the gaming industry with my game concepts and creations. While mapping my plans out the question of where do I start obviously had been brought up, and seeing as the game that ignited my fuel to what is now a wild fire was League of Legends, I thought it the best place to start off my gaming career. However I wanted to hear more from a few actual RIOT employees before doing a whole bunch of research into the job opportunities and positions. So if I may hear your thoughts on what type of conceptual designers does RIOT look for what does it need filled in, where can someone like my self come into play, what do you think is the best way of going about getting to that spot?
