Got it, thought you were on the other part. My mistake, too many threads.You said nothing about 6 seconds, just "characters being able to heal fulling after every combat" (direct quote). And a PC can only take one HP in 6 seconds, so unless we're talking 1st level or a minor damage, that's not full healing.
But neither of those fulfills the requirements of being to heal all the way up every combat even without the six seconds, so they still don't apply.
