^ Non-synergistic builds are usually bad. You don't build MPen because people build MR, you build MPen to deal more damage to people. The lower their MR already is, the more damage that you get out of each additional point of penetration or reduction. Bringing someone from 40 to 20 is significantly less effective than bringing someone from 20 to 0: and I mean the net increase, not the raw damage. Your build depends so much on magical damage (because of Torment), that it's silly to build Berserker's. But Malady needs AS. This is the primary conflict of your build.

AP only keeps up with AD until triple multiplicative scaling comes into play. I agree that an effective ratio of 55% to the first target with Malady, and AP being about 42% cheaper than equivalent AD, combines to give you good DPS potential. But then crit comes to town, and AP loses the single target battle forever. You cannot match IE + Lethality + Frenzy with AP. It's mathematically impossible. AP leaves single target damage on the table, in exchange for a stronger early/midgame.

Thirdly, sustain is via lifesteal for an AD build, which is significantly more potent than Divine Blessing. It's true that it's selfish sustain, but ADC Kayle is necessarily selfish, and it synergizes extremely well with Intervention.

Yes, AP has advantages, and AS/AP is how I play, but you need to be mindful of its limitations and not exaggerate its strengths.

To your build, I'd suggest either committing to Liandry's (which means Sorc and perhaps MPen runes), or committing to AS to feed Malady. If you chase two rabbits at once, you go hungry for dinner.
