Blitzcrank should probably be in line for a new voice-over
His kit is a dated one and the relevancy and health of it can be discussed for a potential future rework, but as of right now Blitzcrank's voice-over is even more outdated than his abilities. His new lore paints him as a working robot that gained sentience and now selflessly helps anyone in need. He saves families and kittens from burning buildings. His voice-over makes him a walking Dalek reference when attacking and his other lines are matter-of-fact classic "robot does not talk like humans do" joke that has been done to death. Some replacement lines that make use of his new lore would be much appreciated. He doesn't even need a huge amount, just enough to replace the number he currently has until whatever future they plan for him.
