Why are there no AD + Armor Items?
Ability power champions have
Abyssal scepter versus mages, that also grants them decent number of AP, Nice cooldown reduction, a lot of magic resist, and also magic penetration AS AURA, so any teammate with magic dmg spell can do more dmg because of the aura that reduces the magic resistance. ( changed to +10% Magic dmg taken to enemies at pbe )
They have Zhonya with great amount of Ap, Decent armor and aggain some nice cooldown reduction. Also has a great passive, that can be used in many ways.
They also have TONS of items for HP + Ability Power
What the ,,AD'' Champions have for hp and dmg is Trinity and Black cleaver, and if you buy both u lose 1 passive, so it wont be in use to buy them, while you can see a lot of people buyng zhonya + abyssal scepter + Crystal + Morello + Rabadon / Echo / Void staff / in ONLY 1 BUILD.
ALSO THE NEW ASSASSIN UPDATE IS GOING OUT SOON, thats update to some ad items, but still we have no items. I like the new item Edge of the Night , that gives 60 ad + 35 Mag res + lethality, Out of combat ms and active for move speed, but still, it gives mag res, while we still have 0 items for AD/Armor..
