What is the logic behind matchmaking in the unranked battlegrounds?
I switched my deck to only 3× s7r4 and 3× s7r2 champs, with everything else being 2-stars, just to finish the omelette quest. I tried this setup 5 times in unranked battlegrounds, and only once did I get matched with someone who felt appropriate for that deck strengtht. The other matches were practically impossible for my current deck, even though they would’ve been quite easy with my normal deck.
So I’m wondering: is the matchmaking based on our game roster’s strength, or just the strength of the deck we’re currently using? I’m not sure about either.
