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.
My guild and I speculated, there's almost like a union when it comes to bad players, you call one out, and the others will get angry with you, as opposed to the under performing guy, just because they are angry from all of the years that they themselves were called out for underperforming. Because of this, they will boot the guy who was actually helping them down the boss, because it's their way of getting revenge against all of the players that used to kick them back in the day. Anyone else ever have an experience like this? Does the bad player union exist?
