[2022] Swiftplay is genuinely amazing

They use MMR!

All our playlists have MMR. We seed your initial MMR when you enter a new playlist from a previous one (we have to start somewhere). The reason we have separate MMR is that some people like to play various modes in their own ways. For example, I use unrated to relax and play with friends, but I use DM to warm up.

Your MMR is made up of half encounter and half win/loss. Well, it's not exactly half-and-half, it's weights are a per-playlist/rank thing. Encounter is based on duels, ability usage, game impact, etc. Win/loss is just if you won or lost. DM, for example, is a lot more encounter MMR based because it's hard to define what "winning" is in DM. So that's another reason each playlist tracks MMR separately; because the weights of each MMR can be different for each mode, encounter:win/loss MMR needs to be set at different ratios, you could have some minor deviations of MMR from mode to mode.

The hardest part about all this is ensuring that when we seed your MMR into a new playlist, we get your skill in a decent spot. We don't always get this right, but we are usually quick to get you in the correct area in 2-3 games(5 at most). For example, you play unrated a lot recently, and your rank is your most accurate with the most played games over the year, it's now difficult for us to know which MMR we should seed from. This is why you may see those initial skill differences when trying a new mode, but hopefully, if we do our job right it doesn't last long.

Hope that helps and have a good holiday season!

(I always like to point out that technically, since MMR exists in all playlists, you could be Radiant in spike rush :P )

Lets gooooooooooooooooo, that's my DM goal LOL
