Hence not starting on the ruins of Halo.
Also there is a problem with this Flood antidote.
" You don't know how this ring works do you? Why the Forerunner built it. Halo doesn't kill the Flood, it kills their food. Humans, Covenant, whatever. We're all equally eatible. " -Cortana, opening cinematic to Two Betrayals.
Basically if the Chief sets off any of the rings, we're all dead.
