Thread about a matchmaking patent filed by Activision Blizzard
Me who always gets them good teammates: AYO WTF DELETE THIS RN.Fuente
overwatch does not use any analysis of chat (voice or text) for matchmaking.
without going overly into details, overwatch match makes on:
--your matchmaking rating (MMR) - this is mostly affected by win/loss, with variance applied for certain conditions (i.e. brand new player, among other things)
again, that's overly simplified. but that's basically it.
