From a viewpoint of a casual player, I see a lot of discussion regarding DPS and HPS parsing. Just about every you tube video about DPS rotations has a parser running. A lot of serious raiding guilds require specific minimum numbers on FFXIV logs.
Now, to be honest, I have never stepped foot in savage. But I just want to understand. If the current savage content is so challenging that people need external programs to measure their performance, then why wasn't it implemented in the game in the first place?
Now the argument that I most often hear is: "because having a DPS meter promotes elitist attitude." It seems like a lazy and weak argument, honestly. Because people are now using external programs as a workaround.
Also, if you implement DPS/HPS parsing in the default UI, at least in endgame, then more players might be encouraged to re-learn or change their rotations.
