Riot Games’ latest League of Legends patch 12.15 gives a much-needed boost to energy champions like Lee Sin, Akali, Kennen, Shen, and Zed, while nerfing Master Yi and Sivir and enhancing engage supports like Leona and Thresh.
The devs are also nerfing Qiyana and First Strike, trying to make them far less effective with the Qiyana First Strike issue on Summoner’s Rift. Riot is reducing the item’s healing powers while nerfing the rune’s extra true damage.
