is better at keeping yourself alive for longer for a few hits or an extra raze than a puny - armour aura. Plus nevermore early is more useful with his spells, also 26.6% (according to playdota.eu) physical damage amplification is useless that early of the game. Also its a sure giveaway that never is near because enemies have the debuff in their status bar. i'm not saying that it's completely useless spell, but rather situational.
