Ohh yes I can attest that there have been people like this. I've been levelling my hated jobs lately to 60 for GARO titles, and so not running as healer as I usually do. I keep seeing people refuse to apply protect, and quite a few scholars who refuse to DPS at all and when asked about why they stand there, say that they made it so healers don't DPS anymore in SHB so they don't have to. >< Why why why.
It's possible it was a troll, but to me, it didn't read like trolling, just terribleness because he kept verbally attacking everyone else for dying from the cleaves or from mechanics(they were new, unlike him) and that seems really dumb because it the things he was saying are very much reportable, who would want a suspension right before expansion? We wiped and I left because I honestly just don't have patience for that kind of thing right now.
