I often find I will be getting shot from behind by someone, so I will press the hotkey for my shield and turn around so they can't hurt me. However I cant see their name and call kos on whoever is shooting me. I think because you cant see peoples names through the shield is why few use it. So my suggestion is to allow us to see names through the shield, agree?
I think most people don't use the riot shield because after 30 seconds of holding it the object clips into you making it easy to kill you. I think that'd be a bit unfair tho, having an immunity to bullets and also being able to see the person shooting.
That is extremely situational and doesnt have much to do with seeing the names, which is important as a detective
There arnt always people around to help. This is why name calling is an important thing you need to be able to do as a detective, which you cant do while wielding a riot shield
