Y'know, eventually, if used enough, the words "John Maclane" in 4e forums the world over will start causing epileptic seizures in people who don't like the 4e healing surges.
I started looking at it, and remembered all my balking at how horribly unrealistic 3E healing was.
Without so much as a stitch of magic, not even a single cantrip, mind you, a character taking a full day's bed rest under a competent healing receives FOUR TIMES HIS CHARACTER LEVEL IN HIT POINTS EACH DAY.
Let me repeat this: Four times his character level in hit points each day.
The 10th level Barbarian with an 18 CON and 130 hit points (well above average, I note), will regain 40 hit points per day of good care. In three days, he's almost completely healed. He could have fallen off a cliff, been chewed on by a demon, and had an Owlbear of Legend hug him to pieces, and he's almost brand-new in three days.
Heck, a 1st level barbarian with 16 hit points will be brand-new in four days. Wizards and rogues? they'll be healthy in one-third that time. That 10th level wizard with a 14 CON and 46 hit points is back to snuff in a single day of being mangled.
healing surges aren't realistic, but they're not that much different from the insanity of everything after Original D&D.
