Yes, they do. This has been confirmed by FFG ... and leads to all kinds of shenanigans.

Well then i guess it comes down the the interpretation of "can not suffer damage in excess of your health".
Similar to the linked uFAQ regarding stamina, that the tokens stay there even if your maximum health changed.
You still can suffer as long as you have the armor/skill equipped.

It's true it's easier and more logic...
but doesn't take into account what FFG has ruled : if one hero with let's say Leather Armor and 1 HP left removes it.. he is immediaty defeated !!!? (don't ask me why .... )

The way we play it, you don't loose a HP when you remove the Armor. It just reduces the maximum you can have.
Ok, if you remove it when you are at max health then you loose one...

It makes sense in the system where you pile damage on your sheet.
The armor increases the amount of damage you can endure.

Like so many things, it's not perfectly consistent. My undersranding is that while stamina and health are lumped together in the rules, different rules apply.

Namely, it is possible to have more fatigue on your sheet than your current stamina (such as if you are fully fatigued and then unequip the ring of power). However, it is NOT possible to have damage tokens in excess of your current health. The difference between your damage and health is your remaining health, and it can never be negative (whereas your remaining stamina can be negative).

If it happens that you would have equal or more damage on you than your health, you are defeated, and any excess damage is ignored. This is why a battlemage could have 1 health remaining, be attacked and dealt 4, recover 1 from dath siphon and not be KO. Those extra 3 damage just disappear.

It is confirmed that if your max health is reduced, you must compare your damage to your new max health and can die (again, excess damage is discarded).

If your health is changed while KO, it is my opinion that your damage would increase or decrease to match. Equipping leather armor while KO would not stand you up. That is, I think my stance is summed up with this statement:

While KO, your remaining health is defined to be exactly 0 and cannot change except by healing.

I agree with Zaltyre here. It's a bit inconsistent but we have to live with it at the moment.

This might help. There are only 4 cases (aside from total health not changing):

You are alive and...

your total health increases: your remaining health increases by the same amount (damage tokens unchanged).

your total health decreases: your remaining health decreases by the same amount to a minimum of 0. (damage tokens unchanged).

You are KO and...

your total health decreases: your reamaining health remains 0. (discard damage tokens down to new total health).

your total health increases: your reamaining health remains 0. (add damage tokens up to new total health).
