During the last beta session I was fortunate enough to get to try more than one class. I tried the Assault first (which feels really good overall), and opening a crate took a long time. Next I tried Medic. Got to a crate and opened it. While Steady Hands did provide a small reduction in opening time, it didn't feel significant. Maybe 7 seconds opposed to 10. It's clearly a bonus there but it's not big enough to feel significant. If you have 7 seconds to spare opening a box, you probably have 10 seconds to spare opening said box. Granted I don't have any hard numbers, this is solely based on feel. I think Steady Hands could use a big buff. Right now it feels like ~30% reduction. It could stand to be closer to 50-60%, since medics don't have much else going for them by way of passives.
