Tech I main drg until recently I didn't tank 6/7 I was drg 6-9 and outside coil I'm usually on drg. But still I cannot out damage my monk playing perfectly in T8 he can curb stomp my dps lol. Not that I care that much since I (like many others will be on ninja anyways.) DRG has its pluses but trying to sell it as "it boosts brd's damage thus it makes up for it" is wrong. As I pointed out earlier, utilizing a second monk provides a better damage out put. You need to run 3 piercing damage classes to make disembowel shine.
