I get that the active matchmaking code is there to make things interesting for players and the deck they're using. You've done this for years with win rates at events, it's fine here. However, PLEASE strip out one element of it: the Archetype matching. Specifically feel free to keep in matchmaking by ranked tier (if playing ranked), win rate in-event (if limited or other events), overall quality or popularity of deck strategy / individual cards in deck / numbers of rares and mythics. All of these serve their purpose well. That said, NO ONE wants to play against matches they hate or are poor against 40% or more of the time, especially when that bad matchup is shared between decks. This greatly magnifies the negative experiences of Arena at the least. No one should be forced to face an 8% metagame deck 40% of the time, a 20% metagame deck 70% of the time, and That One Deck You Always Beat 0% of the time. Sure, always beating that deck may make things boring, but it also validates good deck choices. A random play room should be random. PLEASE disable or greatly nerf this facet of the matchmatching script.
