Custom Games

You have come out with great gametypes like Nemesis Draft and URF, so why not make them custom game modes? I realize it's something to look forward to each year, but I believe that with custom games like this available, you would see an influx in custom matches. I see one HUGE potential factor initially from doing this:

** You thin out the ranked queue's. ** By having custom games like this, you would find the younger crowd of League players playing these sort of games. Maybe they're tired of getting beaten in ranked, or they can finally play with all their friends in 1 game. I just remember playing Halo 2/3 in high school and my friends and I primarily played custom games because it was more fun. Most of us were around the same skill level, so it was beneficial for us to have fun with friends AND get better.

Feedback? What do you guys think?
