Strongest class/job lore wise?

Bias aside, Dragoons are specialized to kill dragons only. Their spiky armor is meant to dig deep through the scales of a dragon, so when a Dragoon dives on top of a Dragon's back, they aren't just shrugged off with a single barrel roll. At any rate, they're mainly specialized against one type of foe only and spend the majority of their training against killing dragons. Even in the Lv52 quest, one high ranking DRG is astounded at how you fight because the way the WoL fights as a DRG is different from other DRGs (probably a subtle reference at our Lancer skills which are Gridanian in nature, not Ishgardian, and possibly our Marauder and Pugilist skills which are needed to unlock DRG). tl;dr DRG are extremely powerful, but only against Dragons which they spend their lives training for, and not really any other type of creature.

This is only partically true, since these things only matter if you're opponent is in or close to the same tier your're in. For example, Tony Stark's Hulk Busters are specifically designed to last against the Hulk(for a while anyway),so hes at a disadvantage in it against someone like Ms. Marvel, who would just fly circles around him and react way faster than he can in it. But she's in or close to the same tier he's in. Tony Stark in Hulk Buster should have no problems taking out Street level opponents like Captain America, Daredevil, or even Spiderman, who won't make a dent on him.
