Why COD is not a "Tactical Shooter":
Respawn
Health Regen
I dont care about the view or perks or airstrikes. But the fact that it is respawn and that it has health regen takes 50% of the danger out of getting shot. When you want to run across the street and get hit and say "Ok, i need to sit here until im at full health again" that means you are getting further and further away from a realistic shooter. When you arent worried about dying as long as you take you man out with you because your going respawn again in 5 seconds then you again are changing the tactical aspect of the game away from reality.
A tactical shooter means that when you play, you do so similar to as if it was a real situation. Yes I am aware nobody plays like their life depended on it so please dont try and twist my words. But in shooters without respawn and health regen there is typically a larger amount of real time tactics used. Just my opinion but when I shoot someone 4 times and they dont die I should not have to shoot them 6 more times after they come back out from behind the wall. It should be 1 shot to finish off the kill, not starting the kill process all over again.
