First person view: Zoom is not unrealistic at all. It is simply the character focusing/squinting into the distance on a certain point, thus removing their peripheral vision.
The crosshairs are stupid, but idk if they could be removed at this point in the game's development.
In some optimal version of the game there would be no 3rd person view, 1st person view would be slid back a bit on the char's shoulders or given a wider FOV, zoom and crosshairs would be removed.
The amount of smarm in this sub-forum is disgusting btw.
