Good comment, i feel like this should be posted in exploit since it's exploiting the game and as someone said above. It's not like this should be happening, when you enter the bounty "kill diablo" you can't afk and hope for the game to kill diablo for you. So this "defending the crazed miner" for you is an exploit. Also, i do not know the exact precentage Also i've had an easy time getting 1B exp/h since i go in group. Solo that might be hard but in group you'll get it basically every time
