I have also noticed that...and I think it's worse than you describe. And no, it isn't strange, it's a BUG because sometimes it works as intended; however, it's most apparent during the fight across the tarmac: the target gets the biotic shielding, but continues to shoot at me! [spoiler alert] Any excuse-making along the lines of "well, they ARE indoctrinated" would be a cop-out. If that were true, Dominate shouldn't work on anyone there. Come on, Bioware! Your adoring fans and paying customers expect and deserve better!
