I do miss them (I'm assuming this is health bar + health packs vs regenerating health btw). It's not about realism either: there is no realism in games. Whether you can take a few dozen bullets to the face, run over a box and are back to normal in a second, or you take the same amount of bullets to the face, run to a corner to cry, and are back to normal in a second, neither makes a lot of sense. The reason I miss health bars is because I miss those situations where you completely get your ass handed to you, there are no health pickups anywhere in sight, and literally everything you encounter next can kill you because you only have 4% health left. Those moments, where you have to be absolutely perfect until you find a health pack, are awesome, and give the whole situation an (dare I use the word) epic quality. You just don't get that when you can shoot, cry/heal, shoot, cry/heal ad infinitum. In fact, that just gets boring in my opinion.
