Matchmaking bug

Just finnished quickmatch game on Temples. Matchmaking created teams like this: Muradin, ChoGall, D.va, Li Li vs. Deckard, Sgt. Hammer, Nazeebo, Probius, MalGanis. So its trip tank vs. trip specialist on huge map where structures are everything. It must be a bug, otherwise I cant imagine matchmaking sucking so bad… Yesterday I played another game and it was trip support. Please fix this.
