@Pedro: Yeah, and it's the A4, which fires only in burst and semi normally. Either DICE should make it the A3 or kill full auto on it. But at least we can add the info.

@Kelleroid: Could be worse. You could just wait like 5 seconds and even if you had 1 HP left, it'd automatically go to 100 in an instant.

If you think about it, 15 seconds is reasonable in a firefight. Who would be able to be in a sustained firefight for over 15 seconds and not get hit more in that time period after first taking damage? But I do agree that the regen rate may be a little fast.
