Blitzcrank's Overdrive rework is beyond stupid, stop beating around the bush
The problem isn't his Overdrive, the damn problem is 
Gut this stupid item already

Yes, let's nerf other every support champion in the game and some mid laners for the sake of nerfing a champion that is played almost exclusively by people who don't support.
Right now, pressing Overdrive allows Blitzcrank to zone for free. He doesn't have to hook, but you need to respect it.
With his current W blitz can go mid when his ADCs back, fire off an extremely dangerous gank that even the best mids in NA are forced to burn summs on in solo que, then b, shop, and be back in lane at the same time his ADC arrives. The roaming potential is excessive when you account for how dangerous his ganks are even through wards
What is so problematic about Mobility Boots?
