The focus of items must shift away from AD shortly
You may be looking at this thread and may be instantly disagreeing. I just wanted to open up a discussion.
For the past few patches, look at the impact ratio of AD-related items to AP-related ones. Most updates have mainly been beneficial to AD champions. With GA being updated, it also makes the item unviable for AP champions as well.
AD champions are getting so many good items that it makes AP champions seem lack luster. Look, I'm not saying the items AP champions are bad or need buffs. However, there should be as much itemization opportunity for them.
First off, AD champions can shred armor[their counter] easily with the items available to them. Black Cleaver, Lethality, Last Whisper, and Critical Strikes[Late game] are absurd. So what's the issue in relation with the burst of an AP champ? It's the amount of itemization to shred. AP champions don't have that much. I believe it's more of a correlation stylistically and lore-wise but there's simply magic penetration and abyssal scepter.
There's also a lack of lifesteal items for AP champs with them only having hextech gunblade. Compare this to the amount of items AD champions have. Don't believe me? There's Death Dance, Bloodthirster, BORK, Maw of Malmortious, Ravenous Hydra, Hextech Gunblade, Mercurials, and Doran's blade.
The amount of AP related items compared to AD related items is NOT an issue actually. However, in terms of VIABILITY, the issue stems from which champions can use said items.
What I want for AP champions is for the items to be as spread out as AD items.
About 2 items is all that's really needed. Maybe another new magic pen item and another lifesteal item would be sweet. Or perhaps an item that provides armor and AP. This will open up the grounds to new builds and champions as well. [Ever wanted an APC with as much lifesteal and damage output as an ADC? This is a chance to make it happen]
Thoughts?


vs 
50 ad + 15% damage is equal to having a 100 ad item come late game
makes LDR do 4.5% bonus AD. WHEW! 4.5%! And here you are trying to claim 45-55.
