Riot Games started testing support item changes on the League of Legends PBE server. Spectral Sickle, Spellthief's Edge and other items were adjusted. Spideraxe revealed these changes on Twitter.
The developers plan to nerf utility support items and buff tank supports ones. Riot Games Tim "Truexy" explained that they do it to balance "the disparity on power between the two support branches".
