I just want to report my personal test about warframe armor type.
I first tested in the simulacrum with lvl105 Electric Crawler alone and Electric Crawler + Toxic Ancient. Crawler alone took my Chroma 740 health with 735 armor down to 200ish in 11 ticks of damage but the Crawler+Ancient killed my Chroma in just 4 ticks.
But that's simulacrum. I don't know whether that is considered "PVE" or not, so I tried again in Gabii, Ceres. This time Crawler alone reduced my Chroma health to ~640 in 6 ticks and Crawler+Ancient reduce Chroma health to ~510 in 4 ticks. I'm pretty sure that this is totally PVE now.
Testing PvE stuff by doing PvP thing... ain't that a bit weird? Well. Unfortunately, nobody want to test it with me so I have to stick to PvE side of things.
I decided to do the easily doable ones so I first went to Ker, Ceres and found a lvl 34 Bombard. His rockets deal 255 damage to shield and 47 damage to health. That's just impossible if my Chroma armor is Alloy.
But there's also TarMOA so I went to Saxis, Eris and found a lvl 31 TarMOA. Its tar deals 12 damage per tick to shield and 13 per tick to health. Again. Impossible for Alloy armor damage modifier.
Hope this will finally clear that armor myth up.
Well there's still a Detron crewman but that one took me 2 and a half hours to finally determine the per pellet damage so, nope, I'll leave that to you.
I sent some PMs to the devs, and Glen responded to me. Here's what he has to say;
"They technically both use Ferrite Armor but the actual damage model for PvP is more complex than PvE Damage 2.0. Beyond per-weapon balancing there is a layer of stat-adjustment that gets applied to soften out the differences in the frames (I'm sure you've already seen this for shields and heath; surprise: it also applies to armor)."
By his statement, Tar MOA are actually worse than I though...
