I'm not sure I'd read that much into one game (commenting about the winning strat). There were a lot of trash players this weekend. Sometimes I'd try things that made me one of them. The fact that your opponents didn't have a counter doesn't mean that it will be unstoppable in multiplayer.
I do agree that there isn't a comeback from a mistake. It's going to lead to a lot of early drops and will be terrible for 2v2+ multiplayer.
..did it in more than one game and saw others do it on stream as well. I don't mean it's totally unstoppable but just very tough to play against and quite boring in general so it should not be doable that easy.
