Blitzcrank "Mini-Rework" Is actually a major nerf.
The fact that you're being punished for using a skill is makes absolutely no sense. It doesn't allow you to catch up to champions due to the "burst" not giving you enough speed to close the gap on a champion that is usually going to well, stay away from you. The fact that it does not give you enough of a gap closer / able to get into position for a good hook in combination with the fact that you're SLOWED after using a basic skill essentially means that if you walk towards someone with you W you're probably going to end up dead from self CC. Blitzcrank was in a good spot and while this change doesn't appear to have the intentions of being a nerf blitz, has in my opinion, been severely crippled.
