it should only apply on champions visible or in combat so it isnt a detection effect. I dont think it is intended as such. I think the intention is getting significant extra defence in teamfights without helping much in 1v1 or even in jungle. Though even in a 1v1 it has the same masterypoints/effect efficiency as Hardiness and Resistance.
