Customizable Custom Games

This thread has been done before in the old forums but I wasn't sure if it was posted here yet. http://forums.na.leagueoflegends.com/board/showthread.php?t=2017963&highlight=customizable+customs

Basically, there should be options for a custom game to be fully customizable to allow for more interactive gameplay. The thread above was posted in 2012 but I think it still has a bunch of great ideas for what we should do and why this should be implemented. Thoughts?
