Loot goblin stealing from teammates mid-combat

ScrapThief99 joins squads through matchmaking and instead of helping fight ARC machines, he just runs around grabbing all the loot drops while the team is in combat. Got downed twice because he took the health packs we needed. Doesn't contribute to fights at all — just waits for loot to drop and sprints to grab it. When confronted, he just leaves the squad and queues again. Classic loot goblin behavior.
