Let the theories begin.
At this site, I found these heroes:
Queen of Junkertown
it will be something meant to balance out the hanzo zarya rein meta by countering the fuck out of half the hero pool and forcing a new oppressive meta as is blizzards policy
In all seriousness I would say it would be fresh, if meta would keep changing every 6 months or so (viewers perspective), but would prefer something similar than OWL Stage 4 meta in Gibraltar. That was fun to watch.
Zarya and Hanzo grav/dragon is pretty boring to watch though.... if it's like every fight either side for whole map....
But funny part is people always said Mercy is easy hero to play before OWL and then you start watching OWL Stage 1 and all of these old Lucio mains playing Mercy and gosh how bad they were :D Just saying.
Teams were also bad at playing around their Mercy so it probably compounded the issue. I also assume that being "easy" or "hard" to play is somewhat less of an issue than actually being practiced on the hero, at their levels of skill at least.
