@SheepsKingFor me its situational, if you’re in an area with us and can relay my teams position to your team I’m going to thirst you. Downed players watching you can give their teammates info on your movement which can mean certain death for you. If I need to pop a bat/cells I’m probably going to thirst. I understand that they can hear it. But sometimes they don’t, sometimes they are popping one as well, cancel the bat and come finish you off mid battery.
Most situations such as the one you said I ignore it. Occasionally i’ll need ammo or a battery, if a downed enemy is near me I’m probably going to thirst and grab one.
