Dragoon is the most popular on my server at least. Why? Kain, thats why...

Theres been a great increase in the number of archers as well, but its still mostly dragoons that I end up with. I also play with a disproportionate amount of monks compared to what I thought I'd see. Oddly, in my dungeon runs the most rare class has been summoner, which I'd never have guessed considering how many I see doing fates.
