HOW THEY GET PICKED
For this list I went through each weapon's attachments excluding the optics, and gather the ones that negatively affect Mobility.
I then sort the attachments from highest to lowest, and collect the highest negative Mobility change for each attachment type.
Some of the optic attachments such as Tactical Scope has -4 mobility but they are all the same on most weapons. On this list I have prioritized other attachment types that affect mobility.
