Planning on using it for Dyna Sandy because I'm sick of eating dirt when I grab hate and get one shot from counter dmg, so should have all necessary buffs.
I really hate to be the bearer of bad news, but the short answer to this problem is simply "git gud."
I wrote a
Short Dyna D Primer earlier, and have mentioned the topic before.
To go into a bit more detail for Dyna-Sandy, it is the zone where I go Liberator 100% for wave 1 and 2, so that I can alternate seamlessly between physical and magical WS, depending on eyes.
This also means that I'm facing down NMs with mythic AM3, and Orcish Counterstance is all but guaranteed to be up.
Taking hate on NMs is not an if, it's a when.
I make sure to announce to my LSmates loudly over discord "MIMS IS ON THE NM's LEFT ARM" when we engage Orc NMs, because whenever it turns to face me, whatever poor soul who wasn't paying attention to positioning ends up eating dirt. I have Drain3 HP, Seigan, Third Eye, a high delay weapon even with mythic AM3, and Dread Spikes. That poor dual wielding Thf/Blm doesn't have a chance in hell if I take hate and they are standing in the wrong place. So let the others know where you are going to be, for their own safety.
Now, for your safety. As in the primer above, Drain3 is love, Drain3 is
life.
After that, Seigan. People talk about Hasso's haste bonus all the time, and it is significant for 55 seconds out of every 4 minutes and 10 seconds. For the other 3 minutes and 15 seconds,
use Seigan.
Seigan will save your life. The mob can't hurt you if it can't hit you. Yes, third eye's duration is random. It may last for 1 attack, it may last for 12 attacks. That is fine, all it really has to do is buy you enough time to get into your DT gear, if you need it.
Now for Orc NMs specifically, engage with Seigan up, and Third Eye down. The reason for this is that Battle Dance will wipe Third Eye leaving it on recast for when you take hate. So leave it down, and the moment that Orc turns to face you, put Third Eye up. With Drain3 you should have enough breathing room even with taking a few hits to the face. Then when you do take hate, just alternate between Third Eye and DT gear as feels safe for you. If you feel safer fulltiming DT gear with an NM in your face, that's fine. If you feel more ballsy about what you can get away with that is fine too, just make sure you are fighting like your life depends on it.
Because it does.
Dark Knight can be exceedingly durable if you let it. My LSmates used to crack jokes when I popped 3 or 4 hour food before Dynamis, and would place bets on how quickly I would faceplant and lose the expensive buff. They don't crack those jokes anymore.
All that said, /Drg is an interesting subjob. I played around with it in Dynamis before SE gave it the WSD trait or tweaked Dirge, but I don't think those changes would change my opinion now. High Jump is neat, but it is hampered by it's 2 minute recast timer. I find myself needing defensive options far more frequently than that, and the fact that I can fit 4 recasts of Third Eye in the space of one High Jump recast suits my playstyle far better. Even against wave3 NMs and the boss I would rather have more defensive control with Third Eye than a hate shedding tool every 2 minutes.
All that said, I think /Drg is actually pretty neat for short zerged fights now with it's 7% weaponskill bonus. For a long event like Dynamis where I have to have more flexibility, I'm /Sam 100%.
