Honestly with the cry of "someone needs to message me so i can get on ae farm" not much can be done to revitalize hazard zones.
I still use them. They have a charm especially perez in the early go. Get to level 6, run perez with whoever decided that begging for a pl for two hours was getting old. Outlevel perez pretty quick and then head to ghostown(boomtown) and out leveling that as well is kinda standard. The contacts and paper missions at that level are old and boring even on redside.
Honestly i kind of wish redside linked to hazard zones. Especially creys folly even if it was just base tp. Then id never switch to worstside.
