I've been enjoying the preseason update, and one of the reasons is because I have more people to play with. Well, when you've got a group of 10 people, it makes sense to play a custom 5v5. We've had fun doing so, but we don't earn any XP for those games. I wouldn't be too upset with this except before the preseason update, you could earn IP from 5v5 custom games. Now, you get no reward for playing a custom game with 9 other people. I think that people should be able to earn XP from custom games (Riot could still use the system that they had for IP, where you had to have 10 people or balanced teams or whatever the system counted) if you have 10 people.
I'd like to know what people think, or if someone could explain why we don't earn XP for custom games. (I have hear people say "Well, people could just abuse the system to get XP." But they could have done that with the previous system and I had never hear of that being an issue in the first place from Riot).
