moving up on leagues

[Kamikaze28]

Since I'm not an official but just a beta tester I can of course neither confirm or deny anything, but I'll try to satiate your curiosity to the best of my knowledge.

No.

It's neither.

League placement as well as promotions and demotions are based on your hidden matchmaking rating and the systems confidence in this rating. There are no fix conditions to fulfill to be promoted or demoted, it is intentionally kept 'fuzzy'.
If you win more than half of your games, you will eventually start to face opponents from a higher league - if you continue to win consistently against these opponents you will eventually be promoted to said league. The system strifes to give everyone a good matchup - which means 50% win chance.
