I am actually kinda unhappy with the changes now, as there was apparently a "glitch" before the latest patch that allowed you to use See-through-Walls tagging with the Authentic HUD in Custom Difficulty. I have been playing like that since the very beginning when the game came out. I like the clean HUD, but I also like tagging.
So... if you could go back to the way it was before the last patch - with Custom Authentic HUD allowing tagging but not showing anything else on screen (Awareness Indicator that starts yellow, then turns red; ammo and health etc.) that would be preferable.
Or just make tagging on/off and option like the aim assist.
I have to admit, this is really, really annoying me. I don't care if it wasn`t intended to be like that, but it was the most appealing option I had to play the game and it's pretty frustrating to have things now changed around. I want an empty screen but be able to tag. I used to have this ever since launch. Now I don't. Annoying.
Oh, and if you don't believe me, you can check this video at the very beginning:
You can clearly see the empty HUD with permanent tagging. I want that back, dammit. I don't want to see awareness indicators or my ammo and health.
