@Riot Can we talk about your rework prioritizations?

Recently you guys have pushed through reworks on Garen, Mord, Darius, Skarner, Fiora and Gangplank. Of those, the only champion who was plagued with low win/pick rates was probably Gangplank. There were a few isolated complaints about Fiora being unbalanced, but none more than people complain about Teemo or Shaco. No one seemed to have any problem with most of those champions, yet they were given the luxury of reworks and attention.

In contrast, we have Poppy, Taric, Urgot, and Yorick, all of whom have been completely ignored by riot despite consistently low win and pick ratios, and despite calls for help on their kits. They are considered toxic when effective, so they've all been nerfed to the point where they are barely viable. I understand that you guys have different people on different projects, but these people have been a consistent problem for years and have recieved no attention. I can find posts as old as 3 years old about how poppy, or yorick, or urgot are all toxic and in need of work, but there have been numerous other champions who really didn't need reworks that recieve them first.

So why is it that you guys work on champions who are already in a relatively healthy (or at the very least usable) state while ignoring ones that you have openly acknowledged as being problematic? You can't honestly say that you've been working on those four for the last 3 years and haven't been able to come up with anything... so why do they get shoved on the back burner?

I would really like some clarification here. As a devoted player, it feels pretty crumby to see primo treatment given to healthy champions while others languish in a proverbial trash heap without any real sign or indication that they're recieving any attention. I know poppy is slated for a rework, as is taric, but why are they so far behind champs who didn't need it, and what about the other two?

Upvote and bump for clarification on this. Thanks for your time.
