I thought in 3e it was 1 hp/level/day. I didn't play 3.5e though so maybe they changed it there. That is about as fast as I'd want to go on healing. I was okay with 1e/2e healing as well.
My primary issue with 4e/5e healing is that it forces one view of hit points. I don't mind a system that supports all views. When a 10th level fighter can recover 55 hit points after a short rest, that is going too far for me. Emphasis on for me. I don't care how others play.
I believe you would be mistaken there. 3e used the Heal skill just like 3.5. I don7t believe there is any difference there. Let me check. According to the 3e SRD:
3e SRD said:
Long-term Care: Providing long-term care means treating a wounded person for a day or more. If successful, the character lets the patient recover hit points or ability score points (lost to temporary damage) at twice the normal rate: 2 hit points per level for each day of light activity, 3 hit points per level for each day of complete rest, and 2 ability score points per day. The character can tend up to six patients at a time. The character needs a few items and supplies (bandages, salves, and so on) that are easy to come by in settled lands.
So, it's still 3 HP/level/day. So, it would take a little bit longer in 3e, say, probably, about 1 extra day. Our 5th d4 and d6 classes would need three days, rather than 2, to completely heal any wound and would still heal most wounds in 1 day.
IOW, no, sorry, you can keep pointing at 4e and 5e, but, that would be wrong. If you wanted slow healing, you have to start with 2e, which also allowed instant non-magical healing, but was limited to (IIRC) a d4 per day, in addition to normal healing rates.
Just out of curiosity, how can a fighter regain 55 HP after a short rest in 5e? He's got 5d10 healing doesn't he? Isn't it level/2 for HD? So, the absolute max, in 5e, he could heal after a short rest is 50 HP, and that would be extremely lucky. More likely he'd heal about 25-30 HP after a short rest and not be able to heal any more damage until a long rest. Given that you can simply change the rate at which HP and Hit Dice are recovered, modifying 5e (and 4e for that matter) is extremely simple.
I guess my question still remains, how much hand holding do you need? How much do you need the books to directly state that your chosen rate of healing is "good"? Considering that your chosen rate of healing hasn't actually been supported in the rules for about fifteen years or so, I would think that you would have found a work around already.
