Warlock tank armor

Hello, I think I’ve noticed a small issue regarding the warlock’s tank rune. It is clearly stated in its description that the armor (generally indicated) is boosted by 500%. However, I have noticed that the armor provided by enchantments (cloak +20 armor) and demon skin (at max level, it offers 210 armor) is not being accounted for correctly.

Currently, I have 324 armor without buffs, and it increases to 1534 armor in demon form. Theoretically, with the 230 base armor from demon skin and enchantment, I should reach 2770 armor. However, I am only reaching 1744 armor.

I understand that 2770 armor is already substantial (considering I have a 40% damage reduction currently), but we are discussing a class that can only evade to mitigate damage, in addition to relying on armor, compared to other tanks that can parry (shaman, paladin, warrior, rogue), block (warrior, paladin) or whose gear is not based on agility and strength (druid).

To clarify, I’m not requesting a buff for the warlock tank, but rather that the information in the tooltip be accurate and clear to avoid any misunderstandings. It could also be a developer error where the armor value is not correct.

I would imagine its just from items, like most other similar effects such as bear form.

Probably didn’t put it in because character count.
