Hello everyone, I was wondering if there’s an optimal range of cm/360 for Warzone that I can try and find what works best for me without playing on some sens that doesn’t suit the way the game plays.

There is none. Sensitivity for any game is a personal preference. There is a reason there are billions of forum posts in different forums about people going mental over the perfect sensitity as well as loads of clickbait videos on youtube.

It all boils down to your preference and lots of practice, no shortcuts, no formula, no magic.

I see that you play at 35cm/360 which is a decent medium sensitivity for games such as call of duty.  It is a good sensitivity to stick with for Warzone, unless you feel the need to change it because can't move the way you want to or you don't have the precision you want. But that is solely up to you and your capabilities.
