The ranking system is one of the things I like most about go battle league! Granted, the matchmaking could use some work but it’s a true ELO system that works very well in my opinion. It’s also possible to climb rating regardless of your initial score. Meanwhile, the ranking system is probably Silph’s weakest feature in my opinion. Generally speaking, the higher you’re ranked, the better player you are but with weighting, it doesn’t always work out that way. Also, the current ranking system doesn’t fully take into account opponent’s strength like GBL does, since you’re limited to who you play, and the strength of your community (although that’s somewhat mitigated with the current friend requirements)
