I keep getting mixed advice for DRK Tanking

[Awful]

Go vitality when you start to lvl as a new tank, once you get comfortable go into str. Once you've played around with how you pull mobs, how many you wanna pull, you can get into "what can I do to keep threat while popping the necessary cool downs to survive". Honestly with the changes right now to str accessories vs vit in endgame I find myself wearing full vit with points into str, I rarely ever wear str off pieces maybe it's because i'm a drk. Who knows lol.

Currently for A4 in my experience you want around 15k hp min as MT (for pld/drk). Can possible get away with lower but I wouldn't recommend much lower than that. I sit comfortably around 16k hp and swap in str accessories. Until tuesday it doesn't really matter one way or the other as there is no "hard" content in the game atm. Everything is story mode and easy mode.

Put all your points in STR, there is literally no reason not to. Whether you use STR or VIT accessories is up to the content you do, and whether or not you are using a pickup group or not. You can currently tank anything in the game with STR accessories, but you need to know how to use your CDs properly and have a decent healer. VIT accessories are more of a safe option, use them when you are still learning(most people wont mind if you do). In my option, it is best to use 3 STR and 2 VIT accessories in duty finder once you know how to play your class.

My suggestion is that the attr points def go into STR, while the accessories should be played by ear. How much time do you think you're buying a healer exactly? with 35 attr points, we are talking about a whopping 700ish HP @ L60. for perspective, my whm cure 1 is a little over 2800hp, regen tick is around 1000-1100hp.

I never argued this, I've said the same--except I consider attributes another "play by ear" as they're easily swapped. But tomato tomato.

So in level 60 content, how frequently are healers letting you drop below 700hp and you end up surviving? (HG/LD doesnt count) Because that is the benefit of your attr points in VIT. STR on the otherhand is helping you the whole time you dps + impacts parry and hp absorb.

Frequency is irrelevant to the point. My issue was with you telling new tanks more hp is a bad thing. There is absolutely no way to determine x # of HP is suitable to all content even if you were to limit it to all "capable" players (which you didn't) because it's dependant on
1) tank ability (even the best PLDs have a difference in mitigation rotations)
2) healer ability (your WHM forgot Eye for an Eye was a thing, and Virus? Sounds gross.)
3) additional damage to ALL players before and after anticipated damage
3) The buffers that sustain us;
- Tank Survivability
- Healer potency
- Support potential

If your tank is always over 1000 hp for every encounter in the game in every situation then you're some sort of god-like WHM, an easier feat for a SCH to carry entire parties this way (or neglect the rest of the party, I suppose) but still god-like, and be that as it may, we can't all rest assured you'll be there to save us. In any case to your point, it's not unusual to come back from any point if HP because skills like Benediction/Tetragrammaton, Lustrate, and Essential Dignity make comebacks like that common enough. In fact they usually sit around waiting for that exact circumstance.

There is no such thing as too much HP when viewing the game in it's entirety. There are times where STR is more viable, but this is not the same thing. I didn't quote your post, I quoted this line specifically because this sort of information being fed to newbie tanks and tanks with issues just butchers our DF.

Here's the thing, VIT really only matters for surviving large hits like tank-busters during boss fights.
