Yes. They also think that 2CP, as a mode, has “fundamental flaws”:
What I’m picturing is a drop down box that allows each player to not be put into that game mode type, possibly for QP/QPC only. You’d only be allowed to sit out of one type at a time - 2CP, KoTH, Payload and in OW2, Push. (I combine hybrid and payload because let’s be honest, the CP in hybrid maps are just flavour and the meat of the level is in pushing the payload.) There’d still be some question of separating players, but considering that one game mode is viewed as problematic by the devs themselves, I think it’s a price worth paying.
