As I said to you in your previous farewell thread (a few months ago?), I wish you the best and will miss your posts on the forum. Not to be too critical, but this post really belongs in The Salt Mines, the scenario you outline isn’t uncommon to encounter on occasions, I don’t see this as particularly useful feedback to anyone here or the any Devs who might be reading.
I won’t defend the MM as being perfect or not needing any improvement. The examples you gave above isn’t something any MM could be programed to consider as it’s mostly a random human behavioral element. Even GM have bad days where their usual performance is poor. A MM also can’t be made to account for fickle human actions like one off trolling or your decision to leave draft for that matter.
Again, I hope you find some joy moving forward. As you said you’re no longer finding HOTS fun, that’s really the only justification you need to leave it behind.
