Would you like an in-game parser?

[Oscura]

What about those that are doing fine but are against parsers on principle, not wanting to be confronted with numbers every step of the way?

Fine is subjective. I'm not defending the mindset of that "anyone who doesn't want parsers is bad," but I've also met people who consider themselves "fine," some of them being Black Mages who never use Fire II during trash pulls or Samurai who have never pressed Hagakure in their life.

Also, just because a parser is readily available, it does not mean that suddenly it will be okay to harass or demean people over their numbers. Though it seems a lot of people consider even just criticism to be "harassment."
