Currently, every player is ranked based on their gameplay from the beginning of the creation of their account to the present.
This does not take into account the fact that some players improve in their gameplay over time, and it also limits our ability to test whether certain kinds of gameplay are better than others
My suggestion is to implement more variety in the ways that we track won and lost ranked games.
For example: winrate in the past year/month/day
also, allow players to create their own game trackers and name them. For example, if i were testing to see whether I am more likely to win when i use OMGUS, I can take every game that i use OMGUS and record that into my personal game tracker.
This allows us to actually test our ideas and see the results.
