Otherwise no one will care or try.
Also I think supports that are already overtuned will be extremely OP in the playtest, I don’t know if I can trust the devs to be honest, especially with how oppressive moira will be for 99% of the players.
Supports need massive nerfs, especially moira if we are bringing 6v6 back. Tanks ofc go back to old health and armor.
How did you manage to make this about Moira?! I am almost impressed.
Fine players (>=plat) had no problem with Moira at her prime without DPS passive and bullet size increase 
the real problem will be illari and kiriko imo. Their attacks are pretty powerful for a 6v6 format. Also mauga.
To be completely blunt the only people who care about 6v6 (and I really do mean care) are primarily old sweats and the very small group of nostalgia. Rank will not matter to either group.
Also, the tests are primarily for Blizzard. Yes, they want to gauge player’s interest in 6v6 as a whole. But the direction of the whole article only points to one way. What are solutions they can do to make current day OW2 better. 6v6 is not that direction.
The only way 6v6 comes back as a permanent fixture is as it’s own separate mode, likely open que. Even then I have my doubts.
