HP washing and the Updates

... so if post-Big Bang HP washing gives even more HP per wash, then wouldn't a pre-Big bang HP washed character be innately inferior to a post-Big bang character as the same number of washes would give more HP to the post-Big bang character?

Or does the patch take into account points put into HP (as a result of HP washing or otherwise) and increase your max HP accordingly?

Also, wouldn't a pre-Big bang unwashed character be inferior to a post- Big Bang unwashed character as well? As far as I know, characters made before the balancing didn't get compensation for extra HP NOT gained through the new AP formulas.
