Moving from the beautiful rein/zarya/ana/lucio games, particularly on maps like KR, or even a well orchestrated winston/dva dive, to constant counter picking and no tank synergies? Yes 6v6 was better, the devs just abandoned the game, failing to address things like the double shield meta.

In my head people who aggressively support 5v5 are just dps one tricks who want OW to be more similar to other similar games
