Something needs to be done about Blitzcrank.

Right now, Blitzcrank is sitting at a 19.2% popularity rate, with a 54.4% winrate, one of the highest of both things in the game -- clearly a problem. Now, why is this? Many things are oppressive about Blitz's playstyle: -His hook. Enemies should NOT be forced to stand behind minions the entire laning phase - especially if he has an ADC like Jinx or MF that deals damage to entire units, you simply can't play against a Blitzcrank. In addition, as soon as Blitzcrank lands the hook, you can kiss that perfect KDA goodbye. His CC, follow-up knockup, and damage combined with the ADC's damage, offer for extremely little counterplay as soon as he hits this one ability. It's simply unhealthy. -His damage. For a tanky support, Blitzcrank deals too much damage. He can 1v1 people mid and late game no problem, and early game, he can delete over a quarter of a champion's health with one combo, something a tank should not be able to do. Combining his high damage output with his tankiness, it is not something a support should have as a gameplay element. SO. What are my proposed changes? -Lower damage on hook and knockup. As stated earlier, Blitzcrank simply deals far too much damage for a tank support. Lower his damage on the knockup during early game, but lower the damage on hook late game. It's a bit of a trade off, but it will make a difference. -Decrease hook's missile speed. Often times, you can't even react to Blitzcrank when he throws out his hook. With champions like Thresh, Nautilus, etc. you actually have time to react when they try to CC lockdown on you, but Blitzcrank's hook moves extremely fast and, with the amount of damage and CC it offers, it needs a lower missile speed to balance it out. Don't make it a super slow ability -- just something that's not a lightning quick grab that offers no reaction time. I feel that these changes are fair, as Blitzcrank keeps his core characteristics and what he is known for as a champion. However, they are toned down a bit, but he still keeps his versatile teamfighting abilities, good laning phase, and, most of all, his pain in the ass hook. Please let me know your thoughts below.
