Yeah SAM gets the cream of every update either gear/traits/JA or enhancments. Y/G/K ignore defense as a HIDDEN effect in addition to debuffing the mob 100% unless they're immune, while WS like Wheeling Thrust and Camlann's Torment ignore defense with TP. Having Hasso/Seigan/Meditate/Sekkanoki as your main job's abilities means you can sub WAR and get Berserk/DA/Aggressor and make the best of both. DRK and DRG main job abilities are meh and rely too heavily on /SAM for defense and TP gain. WAR and SAM abilities compliment eachother EXTREMELY well whereas DRK and DRG have to rely on /SAM and lose out on Berserk/DA/Aggressor that WAR/SAM and SAM/WAR both get.
