Summary
Performance & Technical Improvements
This update focuses heavily on technical stability, introducing a restructured network encoding system to eliminate 'server hitch' frames. Additionally, cosmetic items have been optimized to consume zero network bandwidth after a match begins, which should significantly improve client and server performance during long games. A memory leak related to cosmetic items recreating on every hero respawn has also been resolved.
Hero Balance & Bug Fixes
Several heroes received functional balance adjustments via bug fixes. Clinkz's building siege potential is reduced as Skeleton Archers no longer deal excessive damage, while Slark receives a functional buff as Depth Shroud now correctly applies its intended regeneration and movement speed to allies. Spectre and Muerta also saw fixes to unintended damage and duration scaling.
