I've been avoiding picking up a parser ever since I came back to FFXIV specifically for this reason--after 11 years of WoW I ended up resenting DPS meters more than anything. I've found that I'm much happier judging myself by my own performance (did I handle mechanics well, did I do my rotation properly) rather than strictly by numbers. And I'm much, much happier not being able to see anyone else's DPS numbers--that's information I strictly do not need to care about.

I don't fault other people for using them if they want to, especially savage/ultimate groups where maximizing DPS output really matters. But I hope this game never reaches the point WoW did where it felt like DPS meters were required because everyone was judging you by your DPS.
