After each major tournament, such as the conclusion of ELEAGUE Season 1, Valve takes a good, hard look at what needs to be changed in their quest to make CS:GO Great Again. Mind you, CS:GO is great, I just wanted to use that slogan. However, there is the undying need to improve on any mechanic which they feel takes the game away from it’s natural form, and yesterday Valve served up a curve ball for the CS:GO competitive community.
Spray control became an important feature with CS:GO, where teams would use controlled spray patterns to take duels against their opponents from short to long range. Many players perfected it, and it became synonymous with professional play styles. That has all changed now as Valve have increase “tap” accuracy with the latest patch.
Accuracy Recovery Rate
Accuracy recovery rate determines how quickly the accuracy of a weapon returns to its baseline value after firing. It was previously expressed as a fixed value, but is now split into initial and final values.
Now shorter firing sequences can be designed to recover accuracy faster than longer ones, and the recovery rate for tapping/bursting/spraying can be tuned independently.
TL;DR: This promotes tapping instead of spraying as an accurate one tap will recover your weapon faster, making for a second quick tap straight to the head.
Valve states that the aim here (get it?) is to promote tapping and controlled bursts, something most players originally did, but moved to controlled spray downs as the changes rolled out. This was true for the AK-47, M4A4, and M4A1-s.
