Sacking damage reduction??

[trueido]

many people don't know exactly how it works..
so damage reduction is a special bonus that only ur highest damage reduction take place.

for example if u use damage reduction elix, and heroic fatima (with 20% dmg reduction which doesnt stack) you don't get 45% damage reduction, u get 25% since the 25% is the highest.

but lately there are in the game some "stacking damage reduction" bonuses.
so some people say that if u get 95% damage reduction from glow AA (first sec) and u use like Arcanite Arie AA (15% dmg reduction which stacks) so u basically have 110% damage reduction so u take no damage.
but after some testing, I don't believe that is true..

I believe that for example, if u use glow AA, and u have 95% damage reduction in the first second so u take 5% of the damage (with max armor ofc) and if u combine it with arc arie AA I believe that Arie AA 15% stacking will remove 15% of the remaining 5% damage. which means u will always take some damage as long as u have the highest buff of damage reduction is under 100%.

I wanna get a confirmation from one of the devs about this, if anyone has an additional info please share, TY.
