Anyone else worried about all the mana being added to AP items?

So much CDR and mana being added to items, meanwhile what about champs like Morde? I know a lot of Morde mains that like to sometimes go but now that item has mana.

I personally liked going on galio/Swain when I didn't feel I needed to MR from since GLP gave tankiness and a slow to setup your Q damage, but they removed the HP and just made it a pure AP item.

Just worries me when I see all these items being turned into pure full AP, all CDR items.
