I believe 5-round Stadium is much better than 7-round

There's something about the pacing, 7-rounds feel too long for me, the games feel like they're dragging, rounds are more stompy and it reignites my PTSD that I gained from playing MOBAs all these years ago where you feel the match is just out of your control and it turns out to an endurance test where you need to wait for 20-30 minutes for the suffering to end.

And before somebody says it is because one is QP and the other one is comp - no. I played the 5-round comp throughout its short lifespan and I miss it ever since.

It goes without saying it's just my opinion, I know majority probably prefers 7-rounds, if it wasn't the case Blizzard wouldn't revert the change.
