I keep getting mixed advice for DRK Tanking

[Syzygian]

What I did, and will continue to do, is pump all stat points into Strength. My logic is that it helps my damage and consequently, my ability to hold hate better. More Strength = More Hate, essentially.

Meh argument. There's not a tank in the game that can't hold hate if played correctly even against the most zealous of DPS, I don't care if you're wearing BRD accessories with your stat points in Mind. Also DA Power Slash completely trivializes hate. Do it once, twice, and you can hold hate for the next 2-3 minutes before you need to touch anything that generates additional aggro, even with no investment in STR.

For the OP, do your best to disregard comparisons people are making to PLD/WAR. DRK plays very differently. If you're cross classing GLA/MRD CDs, you have a large total pool of defensive abilties, some with very short recast times. The name of the game with DRK is stacking multiple CDs and knowing when its fluff and when its a tankbuster, and wether its physical or magical, as well as taking advantage of the synergy and large relative uptime of DRK CDs. As far as DPS goes MP directly correlates to damage. MP=DPS. Study your ability tooltips, familiarize yourself with the MP costs/returns of your abilties, and make active use of abilties that the other tanks have no equivalent of, such as Salted Earth, Dark Mind, Plunge, and Abyssal Drain (targeted, ranged, AoE hate-a brilliant tool.)

Remember: Hate>Positioning>Mitigation>Damage. Get aggro, get things into position for the rest of your party to do their jobs optimally, make sure you can handle the damage that comes with the aggro, then deal damage to maintain the aggro. Every tank in the game has the resources to get a solid lead in aggro against one or many targets ahead of equally geared DPS/Healers regardless of investment in damage. Regardless of opinions in the tanking meta and flashy things you can see tanks doing in farmed and/or dated content that they are grossly overgeared for, a tank is a tank and the above is the sequence of priorities, 100% of the time, always, no exceptions. As you get better, hate, positioning, and mitigation will become second nature and then you can focus more on DPS, but still only after those first 3 steps. That's a skillset that you should earn though and not just dive into from day one. Experienced and/or bored tanks love to brag about their deeps and ability to use minimal mitigation and get carried by awesome healers, essentially cheesing content they know like the back of their hand with players they trust for shits and giggles or a challenge. Don't get star-struck by that, and don't be reckless on content that you aren't familiar with. Learn to tank then learn to dps. Keep that mentality and those priorities and your groups will clear content, and if they don't... well, it wasn't your fault.

I do not feel that this is a Meh argument. Especially having come from playing Paladin first with full Vit pumped into my stats and full Vit gear, vs Drk now at 54 with full vit Gear and stats pumped into strength. Two tank classes and one at end game for quite a very long time before 3.0

There is a difference between the classes, yes. But even then I am noticing that I am holding hate much easier on my Drk vs my initial Vit stat tests. Especially against multiple mobs. What you suggest with Dark Arts + Power Slash is likely vs a single mob. And in that case, it is for the most part true. Against multiple mobs however, such an action would reduce your MP to almost nothing very quickly. Of course, I am not saying that you would advise doing such. Likely you yourself do not.

However, to say it is a Meh argument, is quite fallacious. It does make a difference. As a test I recently diverted all of my bonus stats on PLD to Str from it's former Vit. Yes, I lost about 400 HP. But the damage I am doing as a Paladin now, even in shield oath, has given me a noticeable difference. Hate is proving much easier for me to manage vs going full Vit on stats, and Dungeons are quite easier for me on Paladin now as well as that of my group, as everything is getting burned down that much faster. DPS and nukes are able to go full on out with little worry of pulling hate from me. My healers almost always have MP to spare and we can go non stop from pull to pull due to how quickly things die. I have had pretty much zero issues, save for an instance of two extremely overzealous Ninjas in a Dungeon that decided they were the tanks and in their effort to do a lightning quick speed run, pulled everything on them and ate a death or two. While I watched and just shook my head before running in to pull the mobs off of them.

Strength does make a difference, and to say it doesn't I feel is being disingenuous. You are, of course, entitled to your opinion. Perhaps your experience is different. But then again, so is mine. Each chooses their own path. Whether or not they make it work without issue is what matters in the end.

Everything else you have said I agree on for the most part.
