Every year, Riot Games adds, removes, and brings back iconic items to League of Legends to keep the game fresh and dynamic. But, sometimes, tuning items is quite a challenge for the devs. The best recent example of this is one marksman item which was nerfed for three patches in a row, and now the devs are at it again.
After AD carries have lived three full seasons without Statik Shiv, League devs returned this item to the game in Patch 13.10. But, as it turns out, the item was overpowered and a number of mages abused this item in the mid lane. According to League mod, Spideraxe, Statik Shiv has one more nerf lined up in Patch 13.17—its AP ratio will be reduced from 30 to 15 percent.
