For one thing,the humans would not have stomped the Forerunners. The Forerunners were way more powerful. Also,just because collectors use particle beam weapons does not mean their weapons are as powerful as the Forerunners. Fortress-Class Vessels firepower has been estimated at 10 petatons per second minimum,which is 20 billion times more powerful than a reaper. Heck,Forerunner tanks fire in the gigaton/teraton range going by Legends. And seeing as many Forerunner weapons do completely disintegrate thier targets,husks wont be much use. Also, Forerunners have something called Supressors,which can be used to effectively indoctrinate reapers. And unlike indoctrination its pretty much instantaneous.
