I think the most important element for me is that healing scales with base hit points.
It would also nice if all characters had some kind of ability to restore hit points (it makes solo games more viable), but it's not essential. It does not necessarily have to be "healing" either - having vigor points that are functionally equivalent to hit points and are quickly restored (say, with a short rest), used alongside actual hit points which are only restored through magic or days of rest would also be fine. You could even have both options, split up among thematic or class lines - martial characters and barbarians get vigor points, druids, divine and psionic characters get self healing (primal vigor, cure personal wounds, cell adjustment, etc.)
Everything else can be modular. I know what I like and what I don't like, but my tastes aren't universal, and it would be quite selfish of me to deny others options which they would want in their games just because I don't want them in mine.
