I reckon mutagens killed quarantine. If you played quarantine a lot, you will learn to time your sprinting so that the infected will run out of stamina. However,vwith the striker, this doesn't work any more. Similarlyl, you expect a black nade to one shot kill a zombie, but crushers dont. It really killed off free running, with campers with specs and 6 claymores/remote grenades
