Blitzcrank's W change makes me full of the sadness

Let me explain,

Blitz is a polarizing champion, who has a high risk/high reward playstyle. When he is having a good game, he can dominate the fields of justice, and likewise when he isn't having a good game, he can incur the rage of his teammates. I'm sure most players at all tiers of skill have experienced both sides of the robot crap shoot. His whole kit revolves around his Q, the infamous rocket grab, pulling an opponent into his awaiting robot arms, and often leading to CC chained insta-death. However, if he misses his grab, what awaits him is up to 17 seconds of play without his bread n' butter ability. Not to mention the high mana cost that this ability has, which at low levels (and depending on runes/masteries) can be upwards to a 1/3rd of his total mana. The point is that, for a skillshot that can be tricky to land, and mitigated by lane minions, there is a lot of punishment for missing the hook. Now, i'm not saying that it isn't balanced, or that counterplay is bad, and I feel the average player would agree with me. For the potential for wrecking an opponents chances of victory, it certainly needs some risk.

Now, how does this apply to the recent change to his W? In order to comment, I will briefly summarize the change (read patch notes for more details). Essentially, before, his W would give blitz flat movement speed and attack speed. With the current patch of the game, his W gives you a high amount of movement speed that decays over 5 seconds, and flat attack speed. However it also slows him for 1.5 seconds after the steroid wears off. A creative tweak that appears to give Blitzcrank's opponents some more counterplay potential.

I don't like this change for a couple reasons

1. Aside from giving Blitzcrank bursts of speed to move quickly from objectives, his W was also his only real escape tool. The change in movement speed may average out, but the self-induced slow is a nerf, especially in dangerous situations
2. Utilizing his W gives him the ability to position himself to land his rocket grab, which is crucial to the rest of his kit. The change further punishes him if he doesn't land his skillshot, by slowing him down for a second and a half.
3. It just feels counter-intuitive to play. I go fast to then go slow. It doesn't make you feel powerful, and is generally less fun to play.

Now, I don't profess to be a god tier player (I'm not even ranked), nor am I a data crunching theory crafter who knows all the stats and information. I'm just a regular guy who has played Blitzcrank for a long time (the second champion I ever purchased). I tend to believe that how a champion feels to play is a relevant factor that should be taken into account when being balanced. The big yellow robot just feels less fun to play, and that makes me a sad. I believe that champion balance is a difficult and complex thing, but I would like to see some change to his W, even if it meant keeping the decaying movement speed, but only having the slow be removed.

TL;DR The change to Blitz's W adds more risk for less gain, feels counter-intuitive, and is generally less fun to play. Would like to see it changed
