@ xypherous can we have a decusion about the concepts of arrmor/MR penatration VS Hybrid damage

This is a request to ask for a discussion about the overall health of armor and MR as well as Penetration in general. Why it is needed or is there heather options that would diversify marksmen build paths beyond the standard Lifesteal item + infinty edge + PD/statikk shiv+ Last Whisper + boots + defensive item/Mercurial Scimitar.

Would making hybird damage more common and accessible make builds more diverse say Wit's end being stronger or building into something overall stronger with magic damage (example might be 20% of all physical damage dealt is applied as on hit magic damage). In other words instead if getting last Whisper every game this would be an option for countering something like Malphite with Frozen heart and Sunfire instead of just reducing that 145 armor from there items to 94.25.

I know that Lich bane use to apply on hit physical damage if I recall right. Would something like that work for AP building champs.

It just seems like Last Whisper and Void staff in their current state make building anything but purely one kind of damage a joke and as long as they exist in their current state damage builds will always be the same basically every game.

Aka Hourglass + Morello's/Athenes + VS+ Deathcap+ boots+ Abyssal/BV and Lifesteal item + infinty edge + PD/statikk shiv+ Last Whisper + boots + defensive item/Mercurial Scimitar
