[Suggestion] Damage and armor buff/debuff should stack, but until certain percentage

[extrapayah]

after knowing that damage bonus (armor and movement too) doesn't stack each other, isn't it make damage and armor bonus from passive become ridiculously more useless?

and it seems like all damage and armor debuff always negates any damage and armor bonus (e.g. when debuffed with scorn AA, 5% passive armor are negated, not reduced, i was hoping i will only receive 15% armor reduction, instead of 20%)

as because of that, probably devs should make all damage, armor, and movement bonus to be stackable but limit those bonus/reduction into some value (e.g. lowest value of -60% and highest value of +30%)

thanks
