Avoid them if you hate this encounter, they are in very specific square of the world map
You can encounter them in more than one square, but anyway,I don't think it needs to be nerfed because the only tough person there is the assault rifle raider; the others just have normal shotgun and the woman is even unarmed. Just disarm the assault rifle guy and then kill them because their HP isn't that high. They're easier than a pack of ghoul crazies.
BTW I cant use TB when i play PVP...it's too slow.
