It is actually valuable when you realize that the end benefit to self-heals is (mostly) exponential not linear.

If an attack does 1000 base to you and you have a self-heal that heals a base of 500 based on damage dealt, the self heal mitigates 50% of the damage.

If you increase damage dealt and self-healing each by 5% and decrease damage taken by 5%, the attack would deal 950 (95% of 1000) and the self heal would recover ~551.25 (105% of 105% of 500). This mitigates 58% of the damage. A 16% increase in mitigation.

It is not really visible but it is a valuable increase.
