@Riot questions about Hybrid champs and Itemization

All suffer from being hybrid champs but with no clear Itemization.Ive havent seen Riot Talk about Hybrid champs unless its or so ive got a few questions.

has amazing AP ratios and gets the most out of his ablities when building AP and relying on traps but he is built AD in most cases and his Q scales is most effective with AD as well. As AD the clone can be pretty lethal when left to attack a squishy target however when AP clone needs to die to be useful tools to get into close range and slug it out + amazing Ravage buff but poor Ad scaling on everything else which makes 70% of her kit feeling useless

AD being only useful for granting spellvamp. Akali never right clicks you unless she has applied a mark to you.

AD actually pretty useless for the most part on him. He scales the hardest with magic pen and Tankiness. Hungering Bite offers insane sustain and damage when built with AP

good early AD ratios but no tools to actually make use of right clicking also all abilities deal magic damage not physical.

So my questions are....

What are the thoughts behind these champions?

I remember a while back Riot said Warwick was going to be a AP heavy bruiser Is this still a plan? when reworks come will you simply kill off a certain build path (like AP / AP ). Also what about Hybrid Items?Will we ever see something like on Summoners Rift or is Hybrid too hard to balance?

Why are the hybrid pen runes so cost efficient?Will they ever be changed to be more appealing to hybrid scalers?
