Is Blitzcrank in line somewhere for a rework?
I dont think he's top priority by any means, but honestly I think his pull/knockup/silence combo is pretty unhealthy and just unfun to play against.
If he were to get changes, I think his pull should stay in some form (it's too much of his identity to just get rid of or replace), but something thats not just a strictly better Thresh hook. Either that, or don't allow him to follow it up with a knockup and silence.
One idea I had that could be good or bad: Two shorter-range pulls (one for each hand), working on a charge system similar to Vi's E?

) and nerf/change them accordingly while thinking others aren't when in my personal opinion they are moreso. It's just hard to see the justification in what you (Riot) pick and choose to prioritize sometimes.
