Leech and Tur rune

It’s great that leech no longer attempts to heal full health creatures to speed up battles but this change also seriously nerfed Tur rune, which used to heal allies regardless of the attacker’s health. Now, if the attacker has full health, allies do not get any benefit from having Tur rune equipped, because leech does not seem to trigger at all. Can something be done to buff this rune?
