I guess... It's one thing that "one of your own" makes jokes about your game's problems within your group. It's one thing that stream monsters make kappa jokes all the time. But it's another that "one of your own" joins the others and jokes about your game being bad. It feels pretty terrible - regardless of how many are there to witness it and if they know that you're from the same group. This configuration now feels like there's actual malice in it, like a complete lack of decency and respect for the home team.
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
