For a game that tries to be a "Realistic War Shooter" (couldn't keep a straight face saying that), CoD and it's cohorts like the dreadful Medal of Honor: Warfighter decided it's realistic for soldiers to grow their legs back by sitting behind chest high walls.

In Mass Effect 2 the regenerative health actually took a fair time to kick in and you were often encouraged to use the Medi-Gel you were provided with and Mass Effect 3 thoroughly balanced it by splitting the health bar into 5 segments that only regen themselves but not further. Regenerative Shields, Static Health [] is probably the best trope when you want to keep any semblance of realism.
