it'll be interesting to see if they ever show transhumans at their "final" stage like the synths. with their armor and weapons fully integrated into their body. as it is they still require a ton of gear that isn't at all integrated, which doesn't really fit with what we see from the rest of the combine's forces. full integration is the logical outcome, but at the same time their half-finished experimental nature also makes them more horrific. if you make them too synth-y you lose that body horror.
