What are the most and least played classes?

[Altena]

.... as people either learn how the Job ...

I am looking forward to lolDRG being retired and seeing lolSAM everywhere..

From the looks of it, the job has "animation lock" or at least some cast time on the strong/charged skills.
Pair that with everyone being all fresh, and it also being a pretty huge bandwagon job, there will be dead Samurai all over the place!
