So, I'm wanting the most immersive/milsim experience possible and heres some things i had in mind..
-Bring back the task forces.
-Let us create our own patches.
-Let us pick where our patches go.
-Let us pick different patches instead of one that shows up in multiple locations.
-An M50 gas mask can actually be worn with an ACH. I know, I've done it.
-Weapon customization, any picatany rail optic should be able to get equipped on any weapon with a picatany upper rail, same thing goes for all picatany attachments.
-Let us change the stock on all weapons that have a buffer tube.

At the end of the day, I wanna be able to recreate my military experience in game, while also being able to have free reign over customizing my weapon. I want to have the options that are actually possible in real life available to me In game.
