I did LFR the other day and called out a guy that was doing 30k dps. Immediately, the guy responded with a "STFU" and I told the guy that he needed to up his dps, he was pretty upset about it and I said "you're mad because you're bad" or something along those lines. Long story short, I got the boot from the run, despite carrying it up to that point. I talked with some of my other guildies and they told me they encountered something very similar, they would carry the run, and if someone wasn't performing well, anyone that called that person out would get the boot, and the bad player wouldn't be touched. You'd get lots of responses like "it's only LFR", but yeah, we only wiped 5 times lol

I didn't find the right solution from the Internet.
