What decided your main job class?

[Alacran]

Ever since 1.0 I was waiting for Dark Knight, I have always loved everything about the class/ job since the earliest of the FF series days. While I will admit I was initially taken aback by it role as Tank, the chance to play as one in FFXIV has been much appreciated. In a way I guess I already knew how it was going to turn out, my first classes to 50 in preparation of DRK were GLD and MRD back in 1.0 with a sub class THM at 30... before the Job system was implemented. Hoping all those Samurai Tanks get to have the same feeling I do when play my DRK, there's a reason why the person with sword is in front of the enemy, their the Hero.
