Lowkeelloki, Overwatch has had extensive analysis done on it recently after reports of changes to it's acceleration or issues with the ST. What's happening with OW is not the ST because when these are checked the current mechanic has matched the trained mechanic, meaning the ST is still using relevant look mechanic data. The second part of the analysis shows that the STs are linear but because of PS4's low stick resolution on it's controller (128 positions vs Xbox's 32,000+ positions) it can be less clear.
