TRUE REVIEW MUST READ
What killed this game for most players is health increasing from 100 to 150 health, Aim assist is toned down tremendously from MW2, Bullet hit register, heavy focus on microtransactions, Copy and Past from MW2, Campaign, and Zombies, and Charging $70 for a game that could of been a simple DLC, or update.
Main Focus. MW3 Health increasing to 150 Health, Increase the Time to Kill. Players argued that MW2 (Mostly Pro Players) argued that TTK was to short, and Aim assist was way to strong allowing players to melt with little to no effort. Players also complained about the movement from MW2 was to slow, and stiff. Infinity Ward fix what everyone was arguing about.
since TTK increase, Health increase, and aim assist toned down, this require players to be more accurate in their shots which separated the "good from the bad" so they say.
Because of the increase, and increase movement speed, players can easily survived more gunfights due to increased TTK, and toned down Aim Assist
