There are many achivements I've made on and/or for my dragoon. The top 3 that stand out the most in my career as a dragoon as below:
3) 6/07: After a 6 month hiatus due to RL, getting an ethereal earring. Always been my penultimate goal on my dragoon, ever since i saw it as a still growing up dragoon way back when. He was a galka dragoon on a mage SJ and i asked him about his mp management, and he told me it wasnt a problem with his earring. Saw the stats on it and wowed like this -> \o.O/
2) 12/2005: Starting Remora's first all 6 DRG ODS. Coincidentally, this was when our call wyvern was patched from 2 hour ability to a 20 min JA. Mind you at that time, I checked online forums like once/year, (my regular outing into FFXI alla only began back in June 2007 lol) so this was inspired by more of a "what do do with my 8 stacks (and growing) of KS collecting dust in my mog house?" thing. Lightbulb went off, I grabbed 5 of my dragoon buddies with similar stacks of KS, went static, and the rest as we say, was history. The 6 of us went from rags to riches within the next 6 months. When they eventually ran out of seals, (and I was down to about 4 stacks and still growing) I branched out and started playing ODS with every single job combinations possible, pre TAU. Even sent /random /tell to drgs 72+, introduced myself and started recruiting them for future ODS events. Socialized with alot of dragoons back then lol. Very fond memories to this day :) and made it part of my Intro Sig link.
1) I am acknowledged as a Dragoon main in my endgame LS. This was despite the culture of anti drg attitude that was very prevalent among the past officers and members (most of them who i am happy to say quit, got banned, or migrated) and despite the fact that I had other jobs at 75. I wasnt playing back around the pre penta spam days, and spirit link had just come out as a new ability when I first started playing, so I faced alot of uphill battle. I led many of my xp parties, I survived the bias without the bitterness, gathered respect from others as a competent player and a team player, and never gave up making my dragoon as best as it can be. There are other members with 75 drg within my LS, but I am the only active dragoon in my LS to this day. I do participate on other jobs as tactically advisable, but its my drgoon that reaps the rewards. These days, I get more playing time on my drg, for which I'm very happy. After all, you can have more then 1 75, but you only have one main, and for me it has always been my dragoon, since day 1.
