Personally I don't really "get" why people decided to play DRG based on previous DRG characters in other FF games. Kain and Cid to me weren't that great.. I could be missing something, but I felt that Freya was more memorable.

Why I leveled DRG is purely a tribute to lost friends. When ever a friend leaves the game, I make it a mission for me to keep their memory alive by leveling the job they treasured the most. I've done it for THF, RDM, SAM, BRD, next up I think is WHM.

Junyi is the player that inspired me to level DRG. He stuck by the job through thick and thin showing non-believers that DRG could parse up there with all the extremely well geared DD. Unfortunately he never got to see it shine in Abyssea.
