Gave ad and armor? Change the stats a bit so it looks something like this:
35 AD 45 Armor 200 HP
Unique Passive Grievous Wounds: Upon auto attacking an enemy with 40% or lower hp, Grievous wounds are applied to them for 4 seconds, halving all healing.
Cost: 2800
The item would be worth 2560 gold in stats, plus you got the passive.
Thoughts?
EDIT: Fixed some stuff, changed some numbers.
Phife1 votesso atmas impaler?
Xx420n0sc0p3sxX1 votesI mixture between the 2, yes. OFC, this doesn't scale with hp.
Phife2 votesAtmas was an awful item, because when it was strong it was completely mandatory to get an atmas then a warmogs. This would lead to HIGH HP tanks with > 200 AD.
I dont mind hybrid (tank / dmg) items. Theres one for mr / ap (abyss scepter) so why not? What i do think you should change is the fact that executioners calling is a bad item and no one should build it, for any reason.
Riot should make a new item with AD and with Armor. NO crit, no movespeed... just flat damage and defense.
GundayMonday1 votesI would buy that on my tanky bruiser.
Zarxis1 votesLower the amount of AD it provides to make up for it giving a fair amount of defense; the passive (which should be on-autoattack, not like Morello's on-ability-use) is the offense that you want from it. It's meant to be somewhat situational, not general-purpose (like Morello's has become).
Xx420n0sc0p3sxX1 votesWhen I said same as morellos, I forgot about the ability proc, i just got lazy :P. I fixed that.
SmokingPuffin1 votesAD/Armor items are super bad for top lane health. It's basically the same problem as with the old 
-- it's a race to complete the item, and whichever laner gets it first automatically wins the lane.
Xx420n0sc0p3sxX1 votesI thought about this, and it seems that 
/
, 
, and 
/
aren't too bad for laning (Zhonyas is annoying, but not so much in the laning phase)
SmokingPuffin1 votesAD/Armor is a different problem than the other three cases. It's not anything about the stats themselves. It's about the kits of the champions that want those stats.
