Regardless of whether she's actually stronger or weaker, these recent changes are not FUN.
Not to blabber, but I'll just say a few things first about the rework in general:
The new gameplay it introduced is largely fun and cool, and I've enjoyed finding new builds to get it going.
I think it would be better if they kept the original Q, with the new on-hit passive.
Her new Armor/MR-stacking passive is uninspired and, despite stacking infinitely, doesn't add any new incentives and isn't something you play for. It may as well just be Armor/MR per level since its only function is to scale your defenses with the gamestate and doesn't influence your decisions. I'm not saying anything new here.
All that being said, the recent changes are a step back in the fun department.
Her Q is slower and feels more clunky, and it is less compatible with different builds. Not fun.
Her E has higher scaling, bringing her closer to the old E-bot "fantasy." It continues to fall short of the Night Harvester highs, and this playstyle only continues to become weaker, less fun, and less respectable. Fun if you like being an E-bot, but will never be as fun. If this buff to AP scaling is the reason for budget cuts in other areas, then it sucks and is not fun, because it prioritizes a pale shadow of past gameplay over the new fun possibilities we just had.
W keeping the movespeed buff is fun. GJ there.
I've said all I have to say.
