Would you like an in-game parser?

How do people know what gear is BIZ for Savage or Crafting or what the optimal melds should be?

Gear, rotatation and skill of the player are different things. It's nice to have a BiS page, so you know what you should get or not. What I mean is, what if this person with personal parser see he do 900 on his BLM 230, while the one who has ilvl 220 does 1.300. How can he know he's good or not?
