Hey Ilala,
Your question hits on a difficult aspect of the concept of stat weighting.
You are obviously a DK tank, as you are concerned about being D-capped, which is definitely your top priority.
After that, however, your concerns are between three things, threat, max HP, and avoidance.
The stats involved would be:
Threat:STR
AtkP
Expertise
Hit
Crit
Haste
ArP
AGI
HP:STA
Avoidance:Expertise (get parried less)
Defense
Dodge
Parry
AGI
Now the problem is you can't just throw stat weights around and then mindlessly follow the LootRank order, even if you have a defined preference of playstyle. You might accidentally un-D-cap yourself, for example. Or threat-limit your DPS. Or go just below the point where a hard-hitting boss will 2-shot you, instead of 3-shot.
Gearing a tank well is all about balance. Sure you can have stat preferences, but any weakness in your gear (threat, HP, avoidance) will wipe your raid.
With all of this in mind, consider what stats you prefer to emphasize and play around with the stat weightings so the gear that comes up roughly matches what you think is the better gear.
If I were a DK tank (and I'm not) my stat preference might be ranked like this:
(Higher is more important):
Defense
STA
Dodge
Parry
Expertise
Hit
STR
AGI
AtkP
ArP
Crit
Haste
And so my hypothetical DK tank LootRank could be:
