Especially now with the release of the new update and the ghillie suit DLC, I think it would be a good idea if you could assign appearance presets to loadouts.
As an example:
Let's say I make a "Night Operation" appearance preset, and a loadout for my rifleman specialized for the new night maps only! Instead of me having to equip the loadout before the match, then de-equip it when I want to play another game mode or map I can just decide to equip the "Night Operation" preset to my rifleman's night map loadout!
Another example is:
let's assume that I have 2 marksman loadouts, one designed for sniping silently from a long-range, and one for more close-quarters combat...If I make a bulkier, more close-quarter orientated loadout it won't fit with my silent sniper loadout. If I instead make a "Stealthy" or light combat preset it won't fit with my CQC loadout, and on top of that with other classes like demolition and rifleman.
Now obviously this is not something important, and I am sure the developers have more important things to worry about then cosmetic changes and assigning different appearance presets to different loadouts...However, it would be a nice touch, which if they get spare time to work on it...Could be implemented next update?
Thanks for reading and have a nice day
