User Map Settings/ Arcade mode? rito pls

Not going to lie, I was pretty upset when I heard that Riot was going to remove Dominion. Although I personally was not a fan of the actual game mode itself, I came to know and love its custom games throughout the years, especially Hide and Seek.

This made me wonder: What if Riot implemented something like a User Map Setting system / Arcade mode where players could build their own game modes? ( kinda like battlenet arcades and UMS in starcraft )

It may just be a stupid idea of mine, but i think it would create so much more variety of gameplay compared to the whopping 3 we have right now. It would also be pretty cool to see what the league community has to offer. Although it will most definitely come with complications and might not even be possible in the end, I think it is safe to say it is worth a try.

R.I.P Dominion you will be missed
