Hard splitting by levels does little sense especially by hundreds as those have very little correlation to anything interesting. And once a split happened the “global” leaderboard makes no sense as it would mix incompatible points.
But the idea of split is definitely worth exploring as it may work around more problems than it causes and has good potential for a more fun environment. While the basic version is trivial on implementation costs. It might be even run as experiment and falling back to the one bracket system if people like it less.
I’d start 3-5 brackets with /voluntary/ assignment. Meaning before the first pvp game in an event the player choses a single bracket and is bound to it till the event ends. The brackets have can have a level threshold or even a ceiling, but everyone but lowest levels should have a choice.
Each bracket has a different prize structure matching its audience – i.e lowest level could drop minor TS and some R/UR/E cards, while higher ones arcanes, etc. So ideally higher level players would not want to join a lower bracket for the prizes.
Beyond that everything is the same as now, just for everyone the player pool is filtered to the bracket. For implementation it is a single number on the profile and the choice screen – beyond the filtering itself that is no big deal.
The number of brackets, join restrictions and prizes are really the trickier part to decide but it can be adjusted after every event once the infrastructure is in place.
This system would split the meta a bit and create more chance for low level players to fight peers without much magic in the matchmaker algo. Also would serve as incentive for development and become eligible to play in the further brackets.
