Looks like the game, The Division became a line simulation because at points online NPC's can only talk to one person at a time. That means lines within the game. Another problem is that some people just like block doorways to save spots and locations. You can change a feature on your character so no one will bump into you. So essentially you have an invisible human shield protecting you. Best way to use this power? Doing jumping jacks in front of doorways if you're a d*ck.
