I play as DPS. I have never flamed anyone, or even felt the desire to. As a Shadow Priest, I make use of Shadow Mend and Vampiric Embrace to help myself when possible so healer can focus on classes with less self heal. I watch guides and do mechanics fairly well and the more I do something, the better I get at it.

With that context, let me say that I HATE ending up in a group with someone running this addon. It spikes my anxiety so bad that my name might pop up. The first time I encountered it was spiteful week in Plaguefall, and it just kept going off. Most often not for me, but it would be a lie to say never me. Trying to watch the shades and the visual effects for explosions and goo plus constantly seeing if my name was showing up actually hurt my performance. We were not wiping, we timed the key, no one in the group was hostile. I just think it was overall a net detractor and do not think I am the only one who would find that to be the case.

Imagine being in a group in IRL with everyone trying their best and overall doing well, and every single slight mistake, someone yells out "SOMEONE MESSED UP!" If you're someone who is anxious, please consider the impact of your choices on other people who are also anxious and have some empathy, not picking a solution that just shifts the anxiety to someone else.
