reapers win all they have to do is just wait. they would indoctrinate key people in each faction and turn said key people against that faction. once everybody is through shooting at each other harbinger and the reapers arrive to finish off every one and the indoctrinated they would still continue to use to their advantage. PS: don't under estimate the geth. PSS: to it all off before the reapers arrive to finish off everyone chances are the flood would have infected some of each faction causing massive outbreaks in intelligence even if the rings are used chances are tge flood would hide their gravemind well out of the rings firing range. PSSS: add the lapis to this fight
