Why isn't there an AD equivalent of Morellonomicon yet?
Ever since Executioner's Calling was removed, there is no way to counter sustain monsters without ignite. If you were AP, you can just buy
, but if you're AD and you're fighting
or
or for some reason AP
then you need to have ignite or someone else who is AP with Morellonomicon.
Not saying we need executioner's calling back, because it was pretty bad, but it would be pretty handy to get another grievous wounds item for AD champions.

is proof that we can have crazy healing in the game and still have interesting and interactive gameplay, so with appropriate tweaks to less individually counterable sustain we wouldn't even need Grievous Wounds at all.
would also be nice.
?.... Good luck killing that with any item set and a good support peeling for you before you die.

or real bad
depending on the meta, the only way to make them work long term is to remove heal reducing effects entirely and balance healing from there.
or
= Grievous wounds on basic attacks.
