For the First Person Perspective players, that play with no HUD on, it can be difficult to tell if you're bleeding or not. You have to go into your inventory to check you're bleeding most of the time, and every time you bandage, you have to recheck the inventory to check if the bleeding stopped.
I think there should be some feedback for 1pp players, to see some sort of bleeding feedback on their screen, because most of time you can't see if you're bleeding in 1pp, even when looking down at your body
(sometimes you can see if you're moving and looking down, but it's very hit or miss)
