Samsonius, remember the caveat of indoctrination: the more control a reaper exerts, the less capable the subject becomes, meaning less useful. Virtually verbatim to what Saren said about his own indoctrination by Sovereign back in ME1. The technology and/or strategy of indoctrination is something that the other species have not uncovered, and is still assumed to be buried within the reapers. One reason aside from the above stated is that indoctrination is similar to a lobotomy, only it doesn't result in potentially irreversible brain damage and takes a much longer time to achieve than the latter. Those Salarian prisoners back on Virmire in ME1 were indoctrinated... and the isolated Salarian, when my Shep released him, he attacked right after, primarily because he was still under Sovereign's (presumably) control.
