crypto buff

I thought about a useful buff for cryptos drone to make his passive more viable because i had situations where my drone was heared still 90 m away. I would make the sound only hearable within a 50-40 m radius. and on 30 the sound should be hearable but the enemy should not be able to track where the sound is coming from. that would distract enemies and make his passive more viable for example if you hide it inside the storm. give your opinions down below
