Custom Game Mode

I was wondering if we could get more options in the custom game modes. Maybe these options could be added to help make fun custom game modes;

1. Inherent Cooldown
2. Available items
3. Champion damage
4. Available champions
5. Available abilities
6. Level cap
7. Inherent experience scaling
8. Starting level
9. Turret damage and health
10. Mana regeneration rate
11. Health and health regeneration

Reasons why this is good;

Casual gamers have more options No one will complain about damage too high or certain champions or abilities because they can make their own games No one will ask for urf because they can make it whenever they want Could lead to new game modes
