Here's a few offenders of my OCD in order of hate -
Wearing shields on our backs when they're supposed to be folded away like some sort of TMNT. I see this mostly in safe areas on other players characters,
Face masks hovering over your face and not fitting correctly, Some masks fit perfectly so I can't see why all of them shouldn't.
Wrong gun magazines and attachments on loadouts, (nemesis scope on a pistol? come on guys fix it)
Infinate reloading animations of other players characters in safe areas,
Missing magazines on some weapons like the EB,
Special weapon placement on certain backpacks is unsightly,
Improve clipping issues with certain cosmetic combinations,
The high end black tactical shirt bug fix. (Arms are not connected to the shirt with a clear gap).
