Hey, so with the launch of 9.1.5, there is a gamebreaking bug in Ashran.
See for yourself:
As you can see, we killed their boss, but the game did not end!
(People still got quest credit for “Volrath Must Die” fortunately)
What this means is that the only way to win, for the time being, is on reinforcements.
This means that clever strats, like backdooring the boss, are not possible at the moment, as the game only ends when a reinforcements counter hits 0.
Blizzard, please fix this.
