How many talents in your talent tree increase your effective health against physical and magic by an average of 2.78% for one talent point (taking into account you would still have Rallying Cry without it)? The actual practical benefit is much higher since the effective health is applied at the point when it is most needed and not simply used on cooldown.
The answer... none. There is no other talent in the Protection Warrior talent tree that provides a comparable benefit to effective health against both magic and physical damage with only one point spent in it.
