can we get something to combat this BS sustain problem you let get out of control AGAIN?
there's always
Pretty solid summoner spell, really nice addition to any QWER burst, also handy to apply prior to a tank'n'spank fight if you want to cut back on hostile sustain.
there's also always:

- reflects damage Before it's mitigated by armor.
- acquiring 30% life-steal is incredibly difficult with current itemization to combat the 30% thorns assuming 100% armor penetration.
- armor reduces life steal. A 100 damage attack with 20% life steal is 20 HP restored per hit. 50 damage via 50% damage reduction is 10.
It's pretty much impossible to life-steal off of thornmail. Largely due to the whole thorn damage reflected prior to being mitigated by the thorny-tank's armor.
But since Thorns is magic damage:
If you can raise your effective MR (after hostile penetrations) to equal their armor (after your armor penetrations), then 30% life steal will combat 30% thorns.
Which is like, a 6-major item build deal in a game that sees an average of ~11k gold per player, which is more in the 3 major 3k items, 1k in boots, and 1k in the bank when a Nexus explodes.
Finally:
There was an AD Morello equivalent in Ex Calling.
It was horrible.
The removed Ex Calling had a lower purchase rate than even Viktor's Augment: Death - I can't really see an AD grievous wounds item being all that useful either. Like, the old AD morello equivalent was 100% useless with Grievous Wounds being the only major attraction.
Lower purchase rate than Viktor's Augment: Death. Not even all 4 of Viktor's items combined into 1 category, Ex Calling was purchased less often than 1 of 4 champion-specific items, and purchased less often than Rengar's Bonetootch Necklace. Back when Rengar actually had to decide if he wanted to buy it or not.
Think about what you're asking for here man.
