I loved when there wasn't much health regen, but I'd like to point out that, based on the newest videos, it looks like the health regen is fairly standard, actually. You still need medics to top off the buffs, and the health granted by Battle Hardened does not regenerate, but it looks like
all of your base health regenerates now, and not just segments individually. I can't be sure until I've played, of course, but that's what it looked like to me. Unless there are no dividers to differentiate between the health sections, but that just wouldn't make sense, especially since there used to be. So my take is that full health regen is actually back in.
