I think the problem with Kindred's rework is they changed up her play pattern and failed to fix her biggest issue.
The problem with the play pattern is her damage used to be focused on her AAs, but now it scales better on her skills. This isn't a big difference, but it's there. Her autos also used to get better damage and now they get better safety. The other problem is she's always been a bit of a win-more champion, in that from how her passive works, she's either going to snowball or be snowballed against. Riot didn't fix that, they didn't do anything to make it easier for her to get back into the game, and for her autos, they made it worse by making her need 4 stacks to get a little bit safer.
If I could sum up the problem with Kindred as a jungler is that she's very team dependent instead of being a jungler that enables her team. That's why I call her a win more champ.
