I was viewing my most recent defense in the battlelog. In it multiple bugs were present.
Attacking team (him): Tsume Solaris Takumi Brom
Defending Team (me): Zomm Shade Balog Shadowblade
All heroes are lvl 30
Shade uses haunted past on solaris, 1 shots
Shadowblade uses from the shadows on Takumi, 1 shots
Balog uses cry havoc targeting Tsume, it connects on both heroes
Tsume casts soul shred, despite being silenced, connects on all heroes
Zomm uses taste for brains on takumi corpse
Battle replay IMMEDIATELY , showing the red hood girl and message, despite 2 enemy heroes and all of my heroes being alive
The battle log stats page registers all his heroes as alive and all of mine dead, with my heroes inflicting no damage whatsoever, as pictured.
I am not sure if this is a bug or exploit but it is extremely game breaking.
