Wish I could see a screenshot of the banter. Because I feel like I'm not getting the whole story. I've been attacked as a "toxic" person for pointin out a dPS in the group was ignoring mechanics and just relentlessly attacking the boss.

For pointing that out I get "toxic behavior like this blah blah, if you noticed what the NIN was doing the whole time that means you weren't doing enough." I have to defend this claim against me. I say "I didn't make any mechanical mistakes and I assure you my DPS is beyond satisfactory."

I'm the one getting called toxic. Am I suppose to just sit there and let the nin ignore mechanics everytime? And fail over and over?

Not saying you are wrong OP. I just don't want to condemn random Unknown BLM, without context.
