This patch introduced the origin Hextech which brings Camille, Jayce, Vi, and Jinx to the Convergence. Building Hextechs into your team composition will provide answers to enemy teams relying on a single champion stacked with items. On the flip side, when playing against Hextechs be prepared to spread your items out between your champions to mitigate their disruption.
Significant nerfs on champions and items changed the current meta.
