you net people when someone is downed (or when someone chases you down at low hp)same with traps then they have to make a choice spend the 2 seconds going to the guy to free them from the net or getting the 4th person up if they get the 4th person up you down the net guy if reverse you kill the downed guy
this set up forces the entire FT to not shoot you or one person does shoot you and they lose the fight
(i use both fast hands and trapper)
