What sounds are you talking about? directional sound has gotten definitely worse , pros have complained about this , if you mean gun sounds thats subjective.
Crouch coldown , AWP Nerf , AK and M4 nerfs (accuracy decreased and spread increased , rate of Fire of the colt nerfed) just what are you actually talking about?? You're right about the maps , they have been improved except for Dust2 , i really wish you'd explain what you mean by "actions are cleaner" are you talking about the defuse cables? that i'd agree with.
