HP themselves, sure.
But the extension of this to include surges doesn't stand up to inspection.
There was nothing comparable to surges in 1E.
And I still don't see that they are ready to blunder again on that front.
There is plenty of space between 4e style surges and simply having "non-magical self healing". In 3E a fighter can non-magically self heal. It just takes roughly a week. It takes a hell of a lot less time than anything "realistic", but it still takes meaningful time. And it is "non-magical self-healing".
The fundamental basis of surges as a means of restoring HP is a departure from all prior editions. HP themselves being comparable is true and it does nothing to address the issue of surges.
