Then dont call them rankings, call them maybe "activity points". What I'm going for here isn't some daycare style participation medal way of approach. I want for the best players/Clans to have the highest ranks. Activity plays a little role to me. If some clan has better players than others I frankly don't care about their activity. So I made an algorithm that calculates the best clans.

What I'm getting at here is that rewarding activity should be a sepparate goal
And leave the rankings to reflect the actually best clans/players

Ps. It's easy to blame fish and devs, but in the end of the day people just throw ideas at walls and don't do anything concrete with them, leaving the devs to actually figure everything out. If you really want to make this new system in to a thing. Check my formula and give suggestions on improving it or give something concrete.
