Drow ranger deals less damage if target hero has negative armor

[Carbonfiber]

so I noticed in a game that my friendly slardar is useless to me
as every time Im shooting arrows at a target with negative armor the damage of the marksmanship arrows look like they are less than the normal arrows
so I tested it and its true so every time Im shooting at a target with armor debuffs and marksmanship triggers I feel scammed
how is a passive ultimate supposed to make the player sad when it triggers?
is it a bug or its just how it is?
but then how marksmanship deals pure damage if attacking blademail doesnt return it as pure?

iirc, it's not exactly pure damage, but physical which ignores armor (works as if enemy armor equals 0), so
1) it still will be dealing damage as if armor equals 0 even if it's negative (thus dealing less damage) and
2) blademail will return physical damage (not pure)

actually, i feel like there was already something about similar negative armor issues some time ago, but i'm not quite sure what exactly was the problem and if there actually was something about it (might be just deva vu or something from another game, idk)

[shit]

It is how it its. It ignores armor whether its positive armor or negative doesn't matter. And it's not pure dmg, it's physical

[BloodOwl]

that's how the ult works, ignores armor (sets it to 0) for the attack, so if he has negative armor it will deal less damage when it procs

ah, now i remember what was the similar problem: pangolier's passive was about reducing foe's armor to 0... which also affected negative armor that way
