So I'm looking for a bit of...let's say advice? Info from other players? Yeaaaah...anyway I main drk, I'm not bad at the class but I of course am looking to improve dps for my raid group and overall self. My current dps in a9s fluctuates around 1100-1150 w/ grit on, 10s 1150-1200. Of course this all depends on if there are deaths in my group or not, whether I have to pop grit back on. But a couple of questions...

Is waiting a gcd for plunge or scourge to be used with blood weapon worth it?
Example of blood weapon has about 5-10 seconds left, but scourge is about to fall off is it worth it to wait? Same goes for plunge and even salted? From my understanding BW does affect them both.

My group comp by the way is war/drk/whm/sch/brd/mnk/nin/smn
