Need to put some sort of narrative telling who used the HM item to turn a mob in UD hard mode. It is REALLY annoying for someone to ninja do that and you have no idea who to kick. Checked logs, nothing. No text. So other than randomly kicking people until we find the right person to kick out and it stops happening, there is no way to prevent someone trolling you.
lol random evacs are less annoying to me Whoever did it did it 4 times in heroic UD then again in raid started doing it. So it's down to two people who may have done it. But without knowing who, I have no idea who to kick out. Gr.
I can see how this would be annoying to PuRs. I'm surprised the potion wasn't made such that it 'applies something or another to target' so that you could parse that out.
