Blitzcrank Rework?

I'll admit coming out the gate that there is a little salt on my side of the screen here as I love to play more active supports that are much more impacted by being in lane. That said he (it?) is quite possibly the most anti-fun champion, or at least anti-fun support in the game- punishing the enemy lane for doing anything but farming. It almost seems like some sort of masochistic thing to play him. He has a boring, stale laning phase and all but forces the opposing lane to play equally as dull a game as him. Also seems to be a bit of a troll/support-fill pick due to all the taunting that seems to come from his direction.

Anyway, on to the mechanics: His kit is comparatively pretty ragged at this point and I certainly wouldn't mind seeing some changes both to benefit more skillful Blitzcrank players and make him less frustrating to play against. Being able to hook through walls is pretty iconic and I wouldn't want to change that, but the hook specifically could use a range(slight) and hitbox(more extreme) nerf, but while simultaneously adding some more depth to his kit. Two thoughts that immediately come to mind are reducing the cooldown of the hook by X seconds if you land it on a champion to reward skillful play and allow for more follow-up CC rather than the less occasional hard engage. His passive also feels dated/dull at this point- perhaps something based on his current health % to make his gameplay a little more dynamic. Rough example, but:

Adaptive Mechanism While above 50% max health Increases autoattack range and damage. While below 50% max health gain increased mitigation and tenacity. This would encourage a little more active, skirmish-y play and get him some extra staying power if it doesn't go well and he has to run or fight it out to the bitter end. His other skills could perhaps gain unique effects from the passive, similarly based on his health %, but that would delve more into full rework territory rather than a slight modernization.

Anyway, happy to hear thoughts from Blitzcrank mains, particularly regarding the idea of raising the skill cap while making him less frustrating to play against. Thanks!
