I like having goals, especially as someone who is still very unused to higher tier raiding. It's nice to see where I am, which isn't too great right now, and then read into what I'm doing that's so different from the top players once you take out gear differences and the like. Other people's DPS doesn't matter to me and never has unless they're sitting there auto-attacking or are a zero-DPS healer in content that isn't hard enough to justify it. Neither of which require me to use a parser to see.
