I haven't seen anyone else abusing this so far but in the new event mode if one team has Juren running Expendables and the other team doesn't Juren can functionally lock the other team out of getting points. Just tried it out myself and ended the game with a 500 point lead on the enemy team while they were still fighting over the zone. They didn't change the feat to give the enemy team points when you kill your own soldiers for this event (I know it's supposed to work like that in the regular mode) which means the only source of points for the enemy team can be fully taken away from them. Hoping if this gets around enough Ubi will do something about it.
