9/8 UPDATE: In Patch 21.2, we introduced a new system that made it so that
new Battlegrounds Heroes would be guaranteed to be offered each game during
their early access period (as long as anybody in that lobby had Battlegrounds
Perks). The system was supposed to randomly split the offerings between all
people in the lobby with early access, but we’re now aware of a bug that is
making those offerings not random. We’re disabling the new system and going
back to the old early access system for the rest of this early access period
(ending September 14). We expect that the new system will be fixed and ready
to use again in time for the next new Battlegrounds Hero/Heroes.
