ALL GAME MODES AVAILABLE IN CUSTOMS PLEASE!
I think that all the game modes should be available in custom games. For example, Showdown, One for All, URF, etc. would be available as a gamemode choice in the making of a custom game. I can see why there would be problems with this idea though. Making URF a once a year thing makes it a lot more appealing, and this idea takes it away. But I believe having it available 24/7 (customs) would be much more appealing to me, personally. I have some friends who think this would be a great idea too. One saying that he could practice mechanics easier with the low cool downs on urf. It might have problems with unfair teams, since you get to choose your own team, but I still think it'd be a great, fun idea! They're relaxing in contrast to ranked!
