The League of Legends developers have released a new video diary outlining some of the coming changes to the game. The Volibear patch, which just released, will have some big changes to Sivir, the jungle, and in lane.
Sivir will see more power to balance her with more of the other champions in the game. Her changes are mainly going to be in regards to her passive and her ranged abilities, bringing her more up to par with others in the game.
The biggest changes are coming to the jungle, which has received a lot of player feedback from which devs have drawn inspiration. Smaller camps will respawn faster, all of them will now drop buffs, and ganking will be a more strategic choice.
Health potions are getting nerfed somewhat, but the effects of minions during champion to champion battles will be smaller to balance this out.
