Would I say TW has done a poor job of fixing the major issues of the game in a timely manner? Yes.
Would I say the mid/late-game is still overall a luck-based, grindy, unintuitive, exploit-filled, imbalanced repetitive experience? Yes.
But would I say the game is not more enjoyable than release? No. I think the game is more enjoyable than release.
If we look at
this feedback thread we can track TW's real progress on things the community has asked to be fixed, as opposed to just working on random nothings that nobody asked for, or making meaningless tweaks.
It shows that although progress has been incredibly slow as always, since 1.5.8 (roughly 5 months ago) there has still definitely been progress on fixing things that made the game less fun, and implementing things that made the game more fun. Overall, the game is still highly flawed, and it's taking way too long to get better, but it's improved, and they're finally tackling major issues, like sieges. Credit where credit is due.
Maybe the reason it doesn't feel more enjoyable to you than launch is because the actual amount of gameplay improvement in each patch is very small, and so it feels unnoticeable.
