(Spoilers for The Sacrifice) About the Warframes

During The Sacrifice, Ballas had this to say after he explained how the Warframes were created:"Yet their minds were free of the Infested madness. Or so we thought. We set them upon the battlefield, bio-drones under our command. The Warframes... All of them... failures.Surprised? They turned on us, just as you did. And so we had no choice but to commit them to grave.""We had created monsters we couldn't control. We drugged them, tortured them, eviscerated them... We brutalized their minds... but it did not work. Until they came. And it was not their force of will - not their Void devilry - not their alien darkness... it was something else. It was that somehow, from within the derelict-horror, they had learned a way to see inside an ugly, broken thing-- And take away its pain."Before The Sacrifice, I thought that the Warframes were just proxies constructed so that the Zariman children could channel their powers and fight. But from what I can tell, Ballas is basically saying that the Warframes were actual living bio-mechanical suits with emotions - hence why they can feel "pain".The lore that the Sacrifice brings up makes perfect sense if applied to Excalibur Umbra. The Operator, during transference, comforted him when he was grieving from his memories, and so Umbra calmed down and accepted transference. Before, he just rampaged half way across the system.But it doesn't make complete sense if applied to any other Warframe. When we go into operator mode, our frame just stands there chilling, seemingly completely static. If the Warframes are alive, from a lore perspective, shouldn't every Warframe run around when we're in operator mode?I understand why Umbra is more unstable compared to the other Warframes, man's got it rough before he died. But why is he the only one who acts sentient?Even Ordis acknowledges this:"What? The Warframes are Transference controlled. Battle envoys for the Operator to command... I don't understand."Every Warframe, Umbra included, is created from the Helminth strain of the Infestation, yet he is the only one that even moves without the operator. If, for some reason, he's sentient because he's got it rough, that doesn't make sense, because nowhere in the dialogue says this, and Ballas said ALL Warframes are sentient.TL;DR:The information presented from The Sacrifice states that the Warframes are sentient. This contradicts with what is shown in gameplay - all Warframes except Umbra are static without operator control.Of course, I'm not arguing this from a gameplay perspective. I don't want every frame to run around in battle while the operator just chills somewhere else. But if the Warframes are sentient, the game should show it outside of missions right? Like the Operator and the Frame interacting outside combat, the Frame moving around in the Relay/Orbiter when we're in operator mode...
