Well in the quote it says it makes the game easier sooo.. I'm automatically skeptical. I fear snap ironsight shooting under certain distances (obviously much further out than it is currently) will be unstoppable since you wont be able to miss with zoom; whomever pops IS first wins, no amount of movement will cause a miss cause you're so big on a players screen sort of thing.
...and since such 'scientific' efforts were made into figuring out zoom (calipers, football fields), it makes me wonder if the areas that were scouted in Russia were measured exactly (tape measures, building distances) so as to coincide with the now 'realistic' zooming vision; or will the distances in the maps be guessed at based on photos.
Regardless of it being perceived as more realistic, it's all about game mechanics to me, and this just may change how the game feels and plays in a big way. It's like, hey there's an enemy.. let me press the 'make-him-larger button' so i cant miss

.
I wonder if zoom was added because someone on the dev team got tired of people zig-zagging and dodging up-close fire..
