Why Riot should create a Sandbox Mode for Custom Games in LoL?

- It won't increase the toxicity. Why should it? It's only enableable in custom games & not publicly available. If you want to argue that you can find the lobby well then restrict that to only invitation only or password protected lobbies.

- You could figure out bugs more easily& report them. Why? If you find a bug which is maybe combined with a high cooldown summoner spell or activatable item you can recreate it faster. We want a bug free game.

- You could try out mechanics & you can improve your skills. Arguing against this mod because you want people to improve their skill in normal gaming only is not valid because you even increase your skill by just watching youtube videos or LCS livestreams, etc.

- Why not?
