Yes I do.
The main part I think that makes me well suited towards this is my natural creativity and ingenuity. I like to come up with interesting concepts that have never been tried before. The same reasoning that goes behind, "What would be an effective and unique build on this particular champion?" can go into the more advanced thought process of "what would make an interesting and new champion?" And I find myself doing this all the time when playing LoL.
The secondary and still important attributions I consider myself to have is that I enjoy sharing ideas with other people, bouncing ideas off of them, and receiving what input they have to give to create a bigger picture. I'm also incredibly obsessed with my ideas being liked and appreciated. While others may say this just makes me an obsequious attention seeker, I'd like to think of it as even more incentive to make something people would actually like.
It's cool you have ideas, and it's cool you have ambition, but you know about Thomas Edison right?

As in having some sick art skillz to for the concept design artwork or xp making videos show these champs in action could take you a long way to getting your portfolio noticed. You could even work your way up completely unrelated gaming projects and then branch across from these.
