As has been stated many times before,Reapers are not more advanced than Forerunners. Forerunner warships smaller than the Normandy can fire hundreds of gigatons per seconnd, the Mantle's Approach shrugged hundreds of SMAC rounds(each of which carries as much power as 120,000 liquid tungsten railgun shots),and they have weapons that rip holes in reality. They also have a way larger industry,capable of manufacturing an entire battlefleet in hours and building multiple Dyson Spheres in a few centuries.
