Holding my vote for a bit, though I would certainly argue in favor of a layered defense- with a focus on being able to direct key attacks away from the armor rather than face-tanking. I don't think gravitic shielding will be particularly feasible in the early game, given the near future setting with computers and robotics being about par with modern tech.

What is a dream but a hyper-realistic simulation of life? There are, naturally, abnormalities- the brain's way of working through events, recording memories, and filing data. Yet, in general, the world of a dream will feel normal to the dreamer. If they fly, they feel wind on their face, if they run from a monster, they feel concrete beneath their feet. Many individuals are cheated of these unique details upon waking. Quite the pity, considering that a deep and vivid experience of one's own dreams allows the individual to gain a few hours of their life back from that damned abyss we call sleep.
A damned abyss that we may yet be able to exploit. The brain's ability to simulate is, as mentioned, phenomenal- and I wish to put this to use. With mainframe access, a few psychosomniatic drugs, access to sleeping quarters and the cryo-bay, as well as the license to implant neuro-cannulytic shunts into the skulls of our crew, I believe that we can use the sleeping minds of our crew as the basis for a potent system of predictive analytics. The mainframe guides the group dream, starting it from the current time in the real world using all available information and augmented by contributions from crew minds that display low ECF conversion (High ECF conversion indicating the creation of a fictive dream element, rather than the integration of an existing memory into the dream). Perceived time accelerates when dreaming, and the mainframe will attempt to speed the simulation forward as quickly as can be handled by the patient's brains. In this manner, we can create a simulated reality in which time is passing faster than in our reality. Using this, we can attempt something in the collective Dream and gauge its effects. If the effects are unfavorable we can simply roll back simulated time and attempt a different solution. If they are favorable then we can attempt to procedure in the real world.
In a combat environment, we can attempt hundreds of micro-simulations, each comprising only a few minutes of perceived time, in order to predict maximally effective patterns for real world deployment. It's not a perfect reflection of reality, but the accelerated timescale allows the Dream environment to act as a warped mirror that reveals hints of the future.
