steep ruin
When playing as HOST, sentries are able to produce hit markers and when you kill an enemy you get a special bright orange hit marker to indicate that you have killed it.
However, when you are a client you lose out on both of these features. Hit indicators for sentries no longer appear and you only get the orange kill indicator if you 1 shot an enemy with a single hit of a bullet instance. (Essentially making them useless for many guns, especially shotguns since they can never kill with a single bullet instance).
This issue is quite minor for sentries as, let's be honest, they don't really need the hit markers to begin with, however for regular shooting it is incredibly annoying to not have proper hit markers.
I have a proposed method that works really well in the form of a mod, but it would be super helpful if this was in the base game.
