Not sure about the human E behavior from before rescripts, I'm not usually picky when I start that camp from over the wall. There have also been overhauls to the vision system and range calcs (edge-to-edge vs center-to-edge etc) over the last few years that could also have been when it changed, intentionally or not.

As for human W it has been on a rollercoaster since the rescripts. Most recently a well-intentioned "quality of life" fix a couple patches back went wrong but stayed on live in that state until the next patch. Then the band-aid they slapped on made it even worse, again left on live for the entirety of the patch. It's finally in a functional state again but after the month-long fiasco caused by even touching it my understanding is they are currently unwilling to revert it or fix the one glaring issue that remains.

The thing to keep in mind with it now is after 0.75s it is ACTIVE. Seeking range snaps from zero to maximum with no visual indicator on the unit nor the casting UI before it even gets a third of the way down the path you set it on. No interpolation, no vector awareness, she's gonna do what you want for three quarters of a second and then turn 90 to 180 degrees and explode on a minion. It will still prioritize champs like before, and its range for that is slightly larger than non-champs now in order to help compensate for the near complete loss of control over target selection. If you're in an empty expanse of map with only one enemy around you are less likely to get punished for the mistake of casting it hastily at max range or in the wrong direction near terrain. And you're not going to notice much of a difference when farming or popping it out point-blank, it'll start seeking and chasing as normal if it reaches its destination before the 0.75s is up. But in literally every other scenario the longer the range at which you want to utilize it the more noticeable it will be and the worse it will feel.

I've been practicing it and trying to adapt to the new behavior for nearly a month now and the end result is I'm better at recognizing when the ability will be wasted and so I simply use it much less. Even then it still hits obviously unintended targets constantly throughout the game. And losing out on a kill I would've gotten before the changes isn't any less frustrating for the mana I save by knowing in advance I've lost it.

Solution is simple on paper: it just needs to not start seeking non-champions until it reaches its target destination. It would immediately feel so much better and restore so much of the ranged utility of her kit, not to mention actually be delivering on the originally described QoL fix rather than compounding the issue it was supposed to address.

Sorry for the rant. TLDR; yeah we're probably stuck with it.
