Yeah you have to make a backup, because even if you execute everything exactly the way you plan it out, you can get 6 months out from it and decide you don't like the effect it's having on your game. So make a backup. Also, every time I make a major change like that, I copy my entire league folder to a cloud drive first, so if I decide I'm not happy with results I can just delete and copy paste.
