1.) Taking multiple blows; whether it's from claws, swords, clubs, whips, axes, talons, fangs, etc. but going to sleep and BOOM! it's like it never happened.

2.) Taking multiple shots to the torso, arms and legs but crouching behind a structure for 12 seconds and BOOM! you're full healed.

3.) Taking multiple shots to the torso, arms and legs but you grab a medikit or healthpack and BOOM! automatic healing.

4.) Taking multiple blows; whether it's from claws, swords, clubs, whips, axes, talons, fangs etc. but a glowing holy light rains upon you and BOOM! you're better.

5.) Taking multiple blows; whether from a combination of the things already mentioned but eating a piece of food automatically heals all your wounds.

Well?

Farcry 2 had you removing a bullet from your arm

obviously the just stand still for a few secs..just dumb.. I bet Nathan Drake had a bullet riddled carcas after he was finished

The "crouch behind something and instantly heal" method is killing gaming. It's the most casual dumbing down user-friendly piece of crap to happen to any game.

Every other method is an active healing method. You have to find the food, use the food, find the health kit, or the inn, or cast a spell or whatever.

But just "stand where the bad guy can't see you and the pain goes away" is ridiculous.

Foods have always been my favorite though. Like the giant turkeys or bubble gum in Final Fight. Eating your enemies is always the best too.

i guess hiding behind a building for 10 seconds

Adrenaline doesn't heal gunshot wounds to the neck and crotch.

Food

the 4th one, because you just describe Mallow's HP Rain. Can't get more insane than that!

I think this is what makes the "find cover and heal" system great, though: dying sucks and you should be able to play in a way that you aren't permanently boned if you get caught at a checkpoint with low health.

But yeah, it is easily the most ridiculous way to heal.
