Aye, Lich Bane and Ardent Censer are a bit mucky.

I've added a new item that I mentioned to you previous, although I've currently gone for the original version I envisioned. Another reason that made me err away from splitting the effect is that I felt another splash-damage item would clash with Luden's Echo, even if one is triggered with a shield instead of a damage dealing ability.

I've assumed the reason Riot didn't give Revolver an AP ratio because they didn't want people to sit on it, and not upgrade it. Even if that's true I suppose I could question why that's a problem... but I guess they didn't want people just going Sheen + Revolver for the insane on-hit burst and then picking up a Luden's or something. Not that I haven't already seen like 4 Gragas' do this. I have no missed him in mid lane. DISGUSTING damage.

And perhaps. I was trying to keep the old and new Guinsoo's niches active, since both were being nerfed relative to their old items. Phantom Hit and AOE-on-hit damage are two separate items, I feel.
