QM Match Making

I apologize if this is the wrong place to place this, but I was just in a quick match that I feel shouldn’t have been put together so quickly. The match was Alexstrasza, Stitches, Chromie, Mei, Leoric vs Kael’thas, Diablo , Deckard, Lunara, Li Ming. This account was playing Alexstrasza and was partied with Stitches. Chromie was partied with Mei, and I think Kael and Diablo were partied at the end. The queue time for Stitches and I was really quick, under 15 seconds. The match started at ~9:50 PM EST . Hope this helps, Thanks

whats wrong with that match? both team have tank+heal+assassin, one team has more assassin, other has 1 more tank
