How in the hell did Earth's defenses fail in the autumn of 2552? 300 of the most powerful ODP stations in fiction plus Home fleet support should have kicked some serious ass. (Please don't say the Covenant planted anti matter bombs on every single ODP station.) I know Covenant ships are generally more maneuverable than any comparable craft, but Regret's expeditionary fleet should have been pulverized space debris inside the first hour. EDIT: Also, please explain why the ODP grid's petaton kinetic yield is completely ineffectual against the Mantle's Approach while a simple mining survey charge annihilates it? This, along with the inexplicable armor change in Halo 4 endlessly infuriates me. Double Meta Edit: Is this the new Universe Forum as well? If so, cool.
