First off the post wanted a comparison to
but I have a list of defensive AD vs defensive AP items.https://gyazo.com/25e72465847b820eeba7919af91a3bb2

Will be blunt in saying you've stretched the "defensive " category pretty broadly. Primarily in what the item is used for. Do note, just tryin to provoke discussion with a lil constructive criticism. Not trying to b a prick <3
Simply so I ain't too biased, I wouldn't cosider tri force a def item. Because you don't buy it to survive. You buy it to kill shit. Where as you buy deaths dance over blood thirster for the dmg reduction. Or rylai over morello for the slow.

If this has changed, my apologies, you're right.

we have been asking for this for years, i doubt we will ever get it.
Can AD's get an item that gives them Crit,Ad & Mr? Can bruisers get an item that gives them a stasis effect? Can ADC's get an item that has AD, crit & HP with a unique effect to it?
The answer is no. Mages have enough itemization to not need a QSS on top of everything. You need a qss? You have cleanse.
