Which are in higher damand? PAL/DRK?

[Lucky Strike]

I don't know which I should pick but whichever one I do pick I don't want it to be a class that every other person is making it impossible to get a PT.

I heard that DRK were dime a dozen. Don't know about PAL but they are definetly needed in groups.

PLD is by far far farrrr more desired than DRK.
PLDs are in short supply and always get a PT.

PLD, THF, WHM, BRD are the classes that are most desired for an average PT - DRKs aren't really desired much, and there's a lot of them...
