I can’t tell you how many times OP (and others) have ruined threads that 1% related to Mercy. I can’t tell you how many times OP (and others) have taken things out of context (like, “you’re a cult” for example, the postee meant “acting like a cult” but it’s not clear out of context). I can’t tell you how many times they have ignored toxic players that agree with their stance but call out toxic players that disagree across multiple topics.
