Armor Items
Why even keep it around anymore
You already gutted it
Unique – Thorns: Upon being hit by a basic attack on-hit, reflects 25 (+ 10% bonus armor) magic damage, while also inflicting Grievous Wounds icon Grievous Wounds on the attacker for 3 seconds.
Unique – Cold Steel: When hit by basic attacks, Cripple icon cripples source's attack speed by 15% for 1 second._
You gave it 2 passives that do not compliment each other in any way. If it does damage to whoever autoed it, why would you want it to SLOW AUTO ATTACKS
You gave the item with the most armor in the game NOT ABLE TO COUNTER CHAMPIONS THAT HAVE PHYSICAL SPELLS
~25% of all AD Carries build this. Grievous wounds only reduces healing, and this makes up for reflected damage by healing them
Nullifies the damage through heals, and nullifies some of the armor. Also, champs that build this are generally using spells
~23%, ~21%, and ~4% popular respectively. Incentivizes using sparing auto attacks to do mixed damage
The lack of armor wasn't a problem with this one. Generally the problem is that it's passive is a load of crap
If they let you get close to them, there are items to better take advantage of that.
If you want to just stand there surviving to cripple them, it's bad to put on a mana item, due to most super bulky champs not having mana.
Most popular ADCs. If you manage to be able to use it's passive, they will either back off, have you peeled off, or you would have the opportunity to punish them anyway
You could argue it works against them, because they're mixed between spells and autos, but they are generally building lethality, and they are mobile enough to get away
Some have auto attack basis, but generally have spells or auto attack modifiers that will be doing more damage than autos anyway
FINALLY GETTING A BUFF, but you kinda screwed this one up. Tanks probably won't be building this as much as the juggernauts will for doing FREE DAMAGE on their FREE DAMAGE.
Doesn't reduce enough damage to be helpful enough at it's cost. 
GIVE THIS 10% CRIT REDUCTION
Why does this need so much damage? Where's the risk involved with giving up an item slot for more utility? Instead of being situational, it's core on anyone that can build them.
