I despise this attitude with games. I am a gamer, so is my fella, despite the fact I have probably been gaming longer than him, given I am older, he still does this...not to the extreme u describe, but still backseat driving.
I, like u will not play something if I don’t enjoy it, I also log off before I get to the point of rage quitting. There is nothing more likely to make u screw up than having someone breathing down your neck.
He is also forgetting not everyone plays the same style. Some people are forward or aggressive players. Some a stand back and support players, you need both to run an effective game.
Anyway, my sympathies. Hope it doesnt put u off entirely.
