[Greater Holster Customisation]

That's definitely something that's always bothered me. There are a lot of general loadout cosmetic things that I wish would be tied to a specific frame appearance set, but this is one of the bigger ones for me. Adding some gun holster options would be nice as well, since there are quite a few idle stances that leave longer guns clipping into the frame when sheathed.

[Warframe needs Boss Health Bars]

It'd be helpful in cases where the Wolf wanders off or gets stuck in a closet. There've been a couple of times he disappeared on my group while close to death and the only reason we knew he was still alive was because the fugitives were still invincible.

[Rhino's Iron Skin]

It's definitely something that needs a second look. It especially bothers me that the iron skin won't apply to any attachments, which makes them tend to stick out like sore thumbs.

[Individual Mastery Sigils]

I've been using the Mastery Sigil as part of most of my frames fashion since I started playing and part of the reason for that is their relative simplicity compared to other sigils, with straightforward designs with no overbearing effects. Up through Hunter this has been working well for me but the Eagle and up sigils look a little busy to the point of making me not want to rank up any further. Can we get an option to pick a specific rank's sigil to display? Maybe unlocked at the final rank of each tier?
