Well I'm not angry at this mode I am empathetic to the OP. BG is an RNG onion cake. Experienced players can easily do well because the format is oversimplified with very basic strategies for success, r4 or higher you climb. BG doesn't reward high risk plays or comebacks since the card pool is so small. If you fall behind developing in the tavern it's pretty much GG.
I made it to 7k with a very high winrate. And I didn't enjoy the format at all. Mostly because I'm not playing and RNG controls the vast majority of outcomes. I didn't feel challenged winning or losing. I didn't feel good winning either. For those that like this auto format all the power too them. AFK battle games are a thing, a mobile thing. Ironic you can't play this game mode on mobile due to turn delay issues.
