My response to this. Learn to like both. I used to be straight hardcore. But we have come to terms with the fact that if we ever want to compete in treyarchs tournaments.... we needed to integrate into core as well. They both have their perks. hardcore teaches you to be fast on the trigger. Core teaches you precision aiming. they both work to improve gamers.
Personally I would remove the Peacekeeper. That gun is the worst thing to happen to this game since the Scorpion Evo.
I don't play hardcore much, but if they added more game types, I would. HC Domination would be great.
i would change to way it looks and its would be better if u could see like a blood splatter when u shoot the enemy
making it so that if the host leaves in the middle of a game it doesn't kick everyone and also give everyone a 0 kdr for that match. either that you make it so that if people join or leave after the count down hits 5 it doesnt restart the count down =P
i would change everything need to show the blood when u shoot someone get rid of all the hit markers even tho they dnt bother me like iot does with other ppl
