Can I play drk like I play pally

but I see nothing wrong with leading my pull in grit only and turning on darkside once hate is established.

You will not do as much damage in Grit only while using Unleash, which will result in less enmity gained.

Grit is a flat 20% reduction in damage dealt--like other tank stances.
Your damage dealt is now at 80% rather than 100%.
Darkside augments your damage by 15%, and is STACKABLE with Grit, a benefit the other tanks do not get.
Your damage dealt now sits at 95%.
More damage = more enmity.

Next time you run a dungeon, try pulling like this. Even if it's just one pack of trash:
Grit: ON. Darkside: ON.
Unmend > Blood Price > Unleash 3-4 times or during the full duration of Blood Price > Hard Slash > Syphon Strike > Souleater (rotate between mobs here if you wish, but you should have enough hate built up to not really have to).

All my pulls I do like this. I never lose Darkside, nor do I struggle or starve for MP.

You keep rejecting all the advice people are giving you, but have you actually tried it?

You can say it works for you, but I can also say it works for me not to play casters Foe's on BRD. Doesn't change that it's bad practice. None of the stances SAY to keep them up 100% of the time (Shield/Sword Oath, Defiance, Grit, Deliverance...); it's just common sense to do so.

You will

while it maybe less attack power its still more attack power than a pali can get when it pulls the same mob, and unleash works way better than flash, and dps dont have Argo abilities , so its not really possible that a dps would steal hate from a tank in tank stance using a hate ability , Ive done both I have lead pulls just as u say and just found myself wishing I could use unleash a bit more than than that one or two times , so while I will continue to practice leading in with it on its much more convenient to just have more mp to deal with that having half of it when I dont have to , of course I can work with less , but like I said nobody steals hate from me doing what Ive been doing , but having no mp at all or like 100 mp in case something happens is just not something thats worth the small extra damage leading with darkside on to do unleash brings

That's like saying a monk shouldn't use fists of fire because they still do more damage than a bard...

Ive done both I have lead pulls just as u say and just found myself wishing I could use unleash a bit more than than that one or two times

You should activate Blood Price before you ever Unleash, or begin an Unleash spam. I can easily squeeze in 4-5 Unleashes in during Blood Price's duration, and I'm constantly being hit by mobs, so my MP is more or less infinite while BP is active. Even after it runs out, I can Unleash 1-2 MORE times outside of Blood Price and still have plenty of MP left. Then, I exclusively use my Syphon Strike combo, regaining even more. If I am on auto-pilot, and I am not paying attention to my MP, in 60 content, a quick non-DA Carve and Spit gives me back almost 900 MP in itself. More than enough to sustain me until my next Syphon Strike.

and dps dont have Argo abilities , so its not really possible that a dps would steal hate from a tank in tank stance using a hate ability

You say that it's not possible for DPS to steal hate off of a DRK while they're just in Grit after a couple Unleashes? I have stolen hate MANY times off of DRKs because they Unleash 1-2 times, and then don't bother to do so anymore after that. And that's just with me single-targeting the mob they're attacking, or AOEing a large pack down. This has happened when I've been synced down, and it has also happened when I am running Expert Roulette with DRKs in raiding gear. DPS generate hate with their abilities, so I don't really understand what you mean by saying they don't. All abilities have a 1x enmity multiplier on them, and buffs increase that multiplier for each buff you pop. Sure, I can't Provoke a mob off of you on my BRD, but I can still build up hate against you, and potentially rip it off of you if you are not utilizing your toolkit.

while it maybe less attack power its still more attack power than a pali can get when it pulls the same mob, and unleash works way better than flash

Unleash does work better than Flash. That's a given--I think a lot of people agree that Unleash is the BEST out of the three AOE enmity moves tanks have in this game (Flash, Overpower, Unleash). Because not only do you have the 6x enmity multiplier with it, you are also dealing damage to the enemies, only INCREASING your hate gain. Add in the Darkside augmentation, and that's even MORE enmity gained. You said it yourself that your job is the build and hold hate against mobs. Why would you choose to build LESS?

so while I will continue to practice leading in with it...but having no mp at all or like 100 mp in case something happens is just not something thats worth the small extra damage leading with darkside on to do unleash brings

Practice makes perfect. Please keep practicing. It will only make it easier for you in the long run to maintain Darkside's upkeep and your MP. The more you practice, the better you get, and the more you are able to predict "Huh, this trash pack is gonna die soon. I'm only at 50% MP...let's be a little more conservative with my Dark Arts because I did get a little DA+Souleater happy there, and focus more on regaining my MP with Syphon Strike." or "Oh, this mob will be dead in less than 15 seconds. Let's toss a Sole Survivor on it! It's dead, and I got MP and HP back! Huzzah!"

its much more convenient to just have more mp to deal with that having half of it when I dont have to

Again, it can be more convenient for me to jump straight into my opener rather than turning on Foe's Requiem and augmenting it with Battle Voice for casters, but that doesn't change that it's bad practice not to do it.
