Armor logic?

Here is a really annoying one.

We know armor stacks in Dont starve singleplayer, but sometimes, for example a football helmet (80% damage reduction ) and log suit (80%) damage reduction) used together:

If player takes 100 damage:

One armour will take the majority damage (80) and  the other one would take the remainder (100-80) * 0.8 = 16 damage.

(Those hardcore players call them primary and secondary armours)

But remember: There is no rule dictating if the helmet or the suit will always take the majority of damage.

Head/Body armor does not have priority over the other.

It is only determined by one factor: Which armour did you equip first.

Now this is not only confusing, but also quite annoying. It is extremely hard to keep track of.

I do not want to unequip and equip the armours right before I got into a fight.

I constantly think why is this logical and why can't we have the fair damage distribution mechanic as we have seen in DST.

(In the previous example with 2 armor with equally 80% damage reduction, both armors block 96 damage in total, then each armor takes 48 damage.)

Or suppose grass suit(60%)+ thulecite crown(90%) block 96 damage (Calculated from 100 damage hit):

The grass suit takes [ 0.6 / (0.6+0.9) ] * 96 = 38.4 damage.

and Thulecite crown gets [0.9 / (0.6+0.9) ] *96 = 57.6 damage.

And if Thulecite crown's shield is up when taking hit, It grants 100% damage reduction. 100 damage will be absorbed by both armors:

Grass suit takes [ 0.6 / (0.6+1.0) ] * 100 = 37.5 damage,

Thulecite crown gets [ 1.0 / (0.6+1.0) ] * 100 = 62.5 damage.

Crown shield  converts 5% of damage taken by the crown to sanity drain, so player gets (0.05 * 62.5 = 3.13 sanity penalty).

If we substitute the grass suit with Hamlet DLC's vortex cloak(100%damage reduction against non shadow mobs) :

Thulecite crown shield gets [ 1.0 / (1.0 +1.0) ] * 100 = 50 damage.

Vortex cloak gets [ 1.0 / (1.0 +1.0) ] * 100 = 50 damage.

Cloak converts 30% of damage it's taken to sanity drain, so player gets (0.3 * 50 = 15 sanity penalty).

Crown shield  converts 5% of damage taken by the crown to sanity drain, so player gets (0.05 * 50 = 2.5 sanity penalty).

That is 17.5 sanity penalty in total.

I really think this "primary and secondary armor" shananigan is a bug, or a flawed design at best.

Can we please fix this? Thanks:)
