Would you like an in-game parser?

It shows them compared to others of the same job around the same time.

Which includes raiders that go for BiS and socket materia as well as new people who barely meet the minimum requirements for entering. I dunno, I find it hard to compare. Or perhaps more precisely, I find it hard to tell how much is actual gameplay and how much is raw stats. If you're at the bottom, you can probably guess it's not just gear alone that's at fault. If you're at the top, you can generally assume you're not doing too much wrong. But that's really just a very rough idea and not a whole lot more helpful than the aggro bar ._.'
