Sated Devourer ~ So OP that Vayne is now a Jungle Pick
How do you come up with the idea to let on-hit based champions proc their on-hits more often that what they were balanced for? And your "solution" is to reduce the magic damage per hit, as if most of the champs that abuse this item care.
Like... this is how they've been balanced for years. If these champions would have been balanced with more frequent on-hits... they would have it.
This is even worse than Feral Flare
