As a person who finds frashionframe very important, I find it very annoying that some of the Warframe abilities/conditions affect how the Warframe look during mission.
One of the infamous one is Rhino’s Iron Skin, though was changed from the older absurd design, still can be annoying as it completely covers the whole frame in a metallic texture and thus ruining your fashion. This is especially annoying if you are trying to go for a more organic look using one of the textures from the Voidshell skin or by using the Tennogen Mastodon skin, which in both cases you have to compromise your accent color so that the frame remain looking ok while iron skin is active.
Another one that recieves a lot of complaint is Xaku and his fourth ability Vast Untime which essentially erases your fashion during missions as no Xaku player plays without his four. Xaku deserves even more attention particularly due to the recent release of their new beautiful deluxe skin.
Personally, I also find Nidus’ mutated state to be irritating. I understand it’s less offensive than Rhino or Xaku, but having more protruding spikes and thorns isn’t my taste, especially for the deluxe skin.
Finally, the same can be said for Atlas particular for his deluxe skin, since the accumulating Rubble armor does not match the textures of his deluxe skin at all.
A small change that allows us to turn these visual effects on/off in the arsenal much like with some Prime options, will be a great addition for us fashionframe players.
