Your friend on Fenrir isn't the sharpest tool in the shed. :P
I am a 75 COR. Like BRD, it is one of the most demanded jobs in the game. Unlike BRD, it is one of the most expensive jobs in the game. Unless you have the disposable income to spend 30k+ per party on bullets, elemental cards, food, and ninjutsu tools, in addition to keeping up w/ dice and other equipment (3/5 COR AF, for instance, requires purchasing ~400k in synthesis materials off the AH), I'd recommend BRD.
Switch servers to Leviathan, my friend. It's better here. I run full-time with a HNMLS, so I don't have a lot of spare time on my hands, but I (and Levit, Kincard, and Tonelico) can definitely hook you up w/ some friendly, helpful linkshells. You'll have so much fun, you won't even *think* about that silly "Warcraft" game again. ;)
