Balance the game mode

I was replying to this and after, just now do I realize my idea may not be great for one champion but a fun gamemode! Imagine based on a champion you get your damage is already fixed, there is no need to buy ability power or ad.
There is a catch however, your abilities now have the capabilities. To do either a quarter of their damage or double the damage based on luck.
Now that sounds silly but in this mode, you buy balance. It will increase your minimum. Damage. But lower your maximum damage. So you need to think about how much balance you want before going back out and smashing peoples faces for points like on ascention.
Because if you gamble with lower balance, who knows how lucky you may be?
Sorry about poor grammar I typed this on a tablet. Lol
