I'm not sure this is the right place to ask, but why do AD/Armor combo items not exist? Let's say your some form of AD who wants to reduce, say AD from some Assassin, but can't afford to sacrifice AD.
For mage reduction, 
and its upgrade exist, but nothing for AD reduction.
Well, there's 
. Yes I do know it has AP and no AD, but the Spellblade proc is based off your base AD, which is why it exists as part of the Ezreal blue build and a couple other AD champions. Honestly idk why they don't have an item for every combination of stats you could want. It could be that opening up too many build paths would make other items even more useless.
Also it'd probably instantly be only used as first build item on bot ADC's so they could win duels against each other lol. Hell if I know :3
In the past we have Atma's.
And now 
do his job quite good, shield both AD and AP.
An ad/armor item would really suit the bruiser tanks. They would get more hit and more tank from it.
Why is this being downvoted? Even if it's a bad idea, I think this deserves to be seen.
