@Eonwind : I know that you are busy on something else right now Eonwind but i re-did the test with different KFactors. I used the same MAGE char and same spells as in the previous tests.
Note : All the tests without using Relaxing Sleep. (the difference is not that big with or without anyways).
------------------
level 157 Azure Way (without boost) + Will = 400
Realm used = Realm 3 (psychic blow spell)
Stance = Full defensive
KFactor = 50%
MA on
16 sec before beeing depleted (without relaxing sleep)
Ma off
19 sec before beeing depleted (without rela
KFactor = 100%
MA on
13 sec before beeing depleted
MA off
15 sec before beeing depleted.
---------------------
level 100 Red Way (without boost) + Will = 400
Realm used = Realm 5 (Fist of the Volcano spell)
Stance = Full defensive
KFactor = 50 %
MA on
25 sec before beeing depleted
MA off
25 sec before beeing depleted
KFactor = 100%

level 51 Brown Way (without boost) + Intelligence = 200
Realm used = Realm 3 (Stone Fist spell)
Stance = Full defensive
KFactor = 50%

Azure is the only way for which i noticed a difference with & without armor on. Armor shouldn't matter for a mage as he/she isn't mooving at all.
Nonetheless i also noticed that the Mental Stamina restore a bit faster without MA on...
Test with a WARRIOR.
-------------------------------------------------------
Weapons = Light Maces (level 35)
Armor = Complet MA + Helmet (Horned Helm)
Stance :
Normal = 1min04 sec
Aggressive = 34 sec
Bloody = 20 sec
The same
without armorNormal = 1min04 sec
Aggressive = 34 sec
Bloody = 20 sec
See how weird are the results... No differences with or without armor. I wonder if i didn't made a mistake in my testing ?

Or is all the difference in the vitess of stamina restoration ?
