Actually you are wrong. QM tries to draft equivalent teams. If one team has Abathur and TLV, it would make the other team have Tassadar and Zarya.
We broke the “queue rules” that restrict QM. The same rules that still allow it to be a clown-fiesta of inconsistent nonsense. It is “pretend” balance while actually just making frustration. QM has never worked and the only way to even make it remotely work is to severely limit the possibilities.
