Sadly, what Lenwei says is very true. I've PTed with some awesome Dragoons and have always liked them. Unfortunately though, they've become the brunt of many jokes on FFXI. I, personally, like Samurai and Dragoon as my skillchain partners. Obviously, being a Ranger, I always wanna get the best bang for my buck.
But rest assured, should I ever see a Drg seeking my lvl range, you will be picked up before I get a Drk, Mnk or War. Of course, that is if we have a Tank ;)
For my Rng, my dream setup PT has always been Rng, Blm, Whm, Brd, Pld, Sam. Secondary is the same but replace Sam with Drg.
I love Drk as well, especially once we hit lvl 66 *Purrs*
So, for all the Drg's out there in Ragnarok, there is atleast ONE non-Drg that respects you. Only time and continued perserverance will show the others your true might.
Besides, with your Dragon and your AF, *Whistles* that's one hell of a damaging team.
