So far infested quests are pretty much trash. Clear a T2, then reset the quest for infested. Garage with 1 zombie? Now it has 1 regular and 3 feral/rads. And they are all aggro instantly. Hit the quest marker, 4 ferals spawn on top of you. Dead before you can even shoot. Walk in a room, whole house goes instantly aggro. Getting chased by 10+ ferals out of a tier 3 quest is not what I would consider balancing at any level.
