Weren't the collectors basically just scouts, who harvested select members of species/sampled their populations to see which races were worth assimilation versus just plain destruction? i don't think they played any grand desire in the 'safe' harvesting galaxy wide, because the reapers didn't expect any organized resistance.
Normally, the gates would be isolated, and thus, the species easy pickings. That failed due to the events in 1, and without sov's reports, they needed a way to figure out what they were up against, hence the more active collectors and the specific targeting of humans, who had successfully killed a reaper.
Given that the races didn't seem to take the threat seriously, and they lost the collectors, they decided to invade in force, my gues sis counting on the disarray of the species to make the whole thing possible.
Granted, I don't think they counted on ancient superweapons and one damn baddass human to organize the galaxy's forces. Minus the undos of plot choices in 2 and 1, ME 3 played out more or less like I expected. Well, up until the shitacular ending.
