[2020] Preseason Ranked Changes: PBE

Preseason Ranked changes testing on PBEHey all, we've activated some of our Preseason ranked changes on PBE for testing in Ranked Solo/Duo queue which means we'll also be enabling ranked on PBE. Specifically, rolling out the following:

• Inter-division promos have been removed. On promo, leftover LP will now roll over into your next division. Inter-division demotion shielding at 0 LP has been removed as well.
• We've also made some matchmaking algorithm adjustments. This won't be super noticeable on PBE due to the small population size and fewer ranked games played per account; we're mainly looking for bugs.
• For those players at Master and above rank, duo queue will be disabled as part of our Apex duo removal feature.

In order to get more exposure on these changes, we've temporarily disabled normal queues. If you want a refresher on these and other Ranked changes we're working on, head to our most recent Ranked blog: https://na.leagueoflegends.com/en-us/news/dev/dev-competitive-end-of-season-20-preseason-21/
