New Oblivion Orb gives max health; Morello dosen't

So, in the patch notes, one of the new items (Oblivion Orb) provides 200 bonus max health while giving a little AP and some flat mr pen. It is also a component to the "reworked" Morellonomicon, who now provides AP, flat mr pen, a stronger grievous wounds but (!) no max health whatsoever. Why? I'm not telling that Morello should give bonus max health too, I only think that its strange to give such a random defensive stat to the new Oblivion Orb, since its designed with damage as the main idea and that it dosen't bring it with it when used as a component.
