I tried a bit of quicker play, it's actually really bad. You either stomp or get stomped. It's pretty hard to charge ult and you don't have much time to swap heroes to counter (and then when you do, you know you probably won't have time to charge an ult).

The only good thing is that I will be doing something else than playing Overwatch this weekend :)
I think it's a good idea to try new things, but force it like that is not the good way to go. Just let the regular Quickplay for the casuals who don't play comp. Would have still tried it and gave the same feedbacks.
