When the Detective collects the DNA from a body or item. Footprints are applied for 30s/1min to the person that matches. I just feel it would be a bit of an improvement overall for DNA tracking. Although the path finding may become a pain to make. -FreeKillCoupom
DNA is already powerful. I see no need to further buff it. Perhaps it should be a separate item where you equip it and it shows footsteps of EVERYONE for the last 10 seconds.
I think it might cause quite a bit of lag for some users. As previously stated, the DNA scanner is already powerful.
