I had something similar happen to be after launch. Was doing Titan for Relic quest and someone was running a parser, after the 1st wipe I got called out for having low DPS. The guy was rude about it, But a few people stepped in and said that it was low because I kept getting Gaoled.

Parsers are both good and bad, As long as people use them properly. Parsing your friends/FC/Static and trying to help out is fine, But doing it in a PUG and calling people out and being rude about it isn't.
