Bring Back Executioner's Calling and Atma's Impaler
Currently, the only on-the-fly item we have to counter lifesteal is Morellonomicon which is not enough. A 40% health threshold is absurdly easy to stay above and we need a way to counter a Ravenous/Bloodthirster/Warmog's/Visage build. Either give us a replacement item that grants Grievous Wounds or bring back the Executioner's Calling.
Atma's Impaler was the cornerstone of a good Sion build and having it get removed took a massive chunk of damage and armor away from him. Why would you rework a champion, then take away the item that made him useful? What part of that seemed like a good idea?
And while you're at it, get off the Feral Flare kick. Seriously, I'm tired of junglers using Devourer as an excuse to just not help for a half hour.
