I would wait until Alexander before saying Dragoons mechanics isn't good in the current Heavensward content. I know doing Ravana EX as a DRG feels extremely awkward especially when avoiding mistakes, but it is manageable. Ever since I got to lvl 60 DRG it became a much more stressful class, but at the same time, the feeling you get when you know that you pulled off all you moves, oGCDs, and rotation perfectly for the entire duration of a boss fight is extremely satisfying
