I'm responding to the lala from Bryn, who is on my data center. And I'm not the one claiming all players are so horrible that outside of a premade it takes 50% more time to do a single run. As for proof, nothing is ever is purely beneficial. People use parsers to improve, but they also use them to kick people and belittle, or to try and make normal content into a big status race (cough, fflogs.) There's always positive and negative to any change, and you have to look at it honestly. POTD was positive in that it let people get exp solo and experiment, negative in that it let people shortcut normal party roles if overused.
if people aren't honest about stuff, we'll get horrible changes in response. We'll get parsers, and everyone will be wondering why the playerbase still isn't good at raids. The real problem won't get answered.
