Sure, Night Fae is not the only BiS option, but it is the covenant for anyone interested in a better mobility talent.
You haven’t heard about bad luck I understand. Using these healing items when one needs more health and healer is busy healing tank is not hard at all. What makes it challenging is when more damage is taken while said options are on cooldown and more health is needed - while running around on Burning Rush and healer is busy with the tank.
