Okay, one more time. The opponent lost their main hero and all artifacts, and then left the game. If they want to finish the game, no problem. And, in my opinion, the confirmation means that they agree with the result. And calling someone a "BMer" without having played against them seems a bit strange, don't you think? I, for example, always gave automatic wins, including in tournaments.
I apologize... I must have missed something or not read carefully enough... I thought the situation wasn't so clear-cut... I didn't call anyone a "BMer," I just wrote that the situation, as I saw it, smelled like "BMing"... I apologize...
