If you take away one shot headshots that game falls to pieces as run of the mill shooters with heroes, its sets less apart from the likes of CODs and those kinds.
The philosophy behind map designs is showcased in newer maps.
Bomb OBJs (secure area and hostage are not consider main game mode, even thats kinda bull) are all given “buffer rooms and halls” because before, like on the old house, skyscraper, old Kanals, attackers could breach outside walls, plant and hold outside angles with ACOG scopes and defense barely stood any chance because 2 seconds outside as a defender, you get marked but for being outta bounds (rightfully so)
Newer map principles don’t necessarily push windows (those have always been a death trap anyway) but push clearing rooms because you as an attacker have better weapons, ACOGs still have to make it to site, no more thermite an outside wall, smoke flash plant and run back out. The basement bomb OBJ on the ski resort is the key example.
Sound whoring is just a staple to the game as the headshots, in a era of turtle beaches and ESL, this is what it is, can’t be changed. Shootera bring out all the try hards, fighters learn combos and cancels and pixel positions, shooters learn sound, recoils and angles
