These are just two big but simple problems that I encounter in the custom games.
1. Game modes need to show
Now that we have the Proving Grounds, a map dedicated for ARAM, ADAM, and ABAM I think it is time that there should be a category that shows what game mode it is on. First of all, it organizes the games better. Second, you won't have those idiots that don't read the title and go "This is not ARAM? **** this!" So we either need to educate every LoL Summoner to read, or have these game modes sorted with a press of a button.
2. Customs Games should show more than Summoner Rift scores
I play a lot of Dominion. After all I started playing League of Legends when Dominion just came out. So I barely have 60 Summoner's Rift games, and since I have a 50% win ratio, I have 30 wins in Summoner's Rift. The problem with this is when I just wanna have some fun with custom games, there's always more than a few ****** bags that are picky on game stats. I'm sure they are worried that their non-existent Custom Game ELO will drop.
