First of all, I would like to start by saying that halo 4 exceeded my expectations on all levels. It is an amazing game. Literally the only thing I would change in the game is the scoping mechanics.
Staying scoped in while taking damage is kind of lame. When its a mid-range fight between players with a br or dmr, I can live with it. What really grinds my gears is when you are laying down fire on a sniper. They can take 2 or 3 hits while casually lining up a shot and blow your head off. It gets kind of ridiculous when you take into account that the hitboxes are also bigger.
tl;dr - you should not be able to stay scoped in while taking damage.
