Maybe also ad a button for removing all the gear on the player

Yes, there is a lot of improvements to make for the Arsenal.
Some things that I didn't mention (since less important) were :
-Do not auto add attachements to weapons.
-Do not keep showing attachements when there are none (go to a profile, put an attachement on a weapon, load another profile with the same weapon but no attachement... boom! the attachement appears as if a part of the profile...)
-Do no auto add item when clicking the category (ex: auto adding Binoculars simply because I clicked on the category.)

And that's just some of the many things that could be improved.

+1, especially to being able to categorize loadouts by faction. I have multiple loadouts for each faction, and being able to categorize them would be really handy instead of sorting through a big list of loadouts.

A show load % of current equipment would also be handy.

I agree with showing the weight of the load. While it can be checked by testing the loadout, seeing the weight without having to load the VR world would be neat.

+1! BI please listen to that feedback
