Hi. So i noticed some ppl can throw frag gren even from a close distance and it detonates immediately. How is it possible? Sometimes i threw it and hit melee guys torso or havocs back and it just fall on the floor without detonation so they still have time to escape/dodge. Even when im throwing from far distance for maximum range theres still a small delay. And i died alot from ppl throwing on me from a close distance and it look like it detonates right after touching my body. Can someone explane please?
