That said, I think he is in a fine state right now and doesn't really need any nerfs/changes in the current meta.
Champions with 54% win rates, 16% pick rates, are not in a fine state. A support without a single losing match up (except Trundle for some fucked up reason) are not in a fine state.
A good Morgana/Sivir player can almost entirely nullify the effectiveness of Blitz
League isn't DotA. The core concept of champion balance in LoL is that there are no hard counters to champions, that as much as possible match-ups aren't won and lost at champion select.
So saying you have to pick two champions out the dozens and dozens that can be played in the duo lane just because the other team picks Blitz, ignoring either team's composition...well, that's just about as useful as saying just engage when his hook is down. It's a suggestion that in practice is much more difficult to implement than in a perfect bubble of thought.
that wouldn't fix much tho, would just be a nerf at best i guess, but since it's moved into e it's not like you made his dmg significaly lower
It would fix a ton. Less damage during laning phase which means trades not going so easily in his favour. That's the entirety of Blitz's schtick - forcing very favorable short duration 2v1 situations. Shifting some of that missing damage to E instead pushes that damage to the mid game. No change late game because he's relying on his teammates damage at that point when he manages a pick and not his own.
Barring a rework Blitz's kit doesn't offer that much room for non-numbers, impactful nerfs. If we're talking rework, than make Blitz Q charge up like Varus, Vi, etc. and adjust it's power accordingly.

The thing about blitz is even though his w got nerfed, coin got buffed so that basically gave his w back to him.
Fun fact: his win rate with FotM is higher than with Talisman. The nerf didn't hurt him much at all once people adjusted. Similar thing happened to Talon with everyone flying off the handle about the removal of his silence.
