I keep getting mixed advice for DRK Tanking

[GeekMatt]

People suggesting STR for tanks aren't wrong, it's just misleading to passerbys reading the forums.

Tank priority is
Manage Aggro > Survivability > DPS and Support.
If you don't manage aggro, you're of no use to the party and are probably dead anyways.
Once aggro is managed, the goal is letting the healer keep you alive, focus on this.
If and only if the first two priorities are confidently met, should you start working on DPSing more and focus on whatever additional support your tanking job has to offer. More DPS means a smoother run for everybody, but if your healer is struggle-busing then it's not worth the trade off.

Start with all VIT and all your points in VIT once you hit 50. This is the safest route to go while you're learning.

When you've got an idea about how much HP you actually *need* for any bit of content, you can start swapping in some STR accessories/attributes.

This is actually how to make it smart. You shouldn't brainlessly listen ppl saying "real raid tank go full str u noob", or "got all vit and get sturdy".

Start with all vit, try and gradually swap one piece of accessory at time if you feel you don't need so many HP.

You can consider turning progression points from vit to str using Keeper's Hymn instead of swapping an accessory as it about same amout than one (about 30 str/vit).
