Instead of changing the whole ranking system. Make it quick and easy.

6 days a week you can try to increase your "esport" rank. The 7th day there is a automatic tourney which gives the winner x amount of rank points

1. The only way to increase rank is to beat a higher or same rank player
2. There is no losing rank points
3. After each month, it resets but all the information stays
4. Whoever has the most points at the end of that month is the best for that month.
5. Basically whoever wins the most tournies.

Cant be that hard to code right? This is just combining many toribash odeas into one like automatic tournies and instead of giving tc, they give rank points
