I've been playing around with anydice more, and over the past couple of days have realized a fault with skill checks. As is, characters at most might have like 8 effective value with skill checks (5 Attribute + 3 Skill Ranks)- while this is okay in personnel combat, and having attacks miss a decent portion of the time, it is less so fitting for trade skills. Who wants to fail in repairing a mech or diplomacy 50% of the time, especially when trained in it? To this end characters may now take a couple of hours, or a day, to receive a -1 or -2 modifier to their roll. That should even it out a bit.
It should also be noted that many of the maneuvers from mech combat (Kneel, take cover, aim, etc.) are also performable in personal combat. Personal combat still needs to be heavily redone in order to be more gritty, and in-depth, but this should still help improve it that much more.
