"Reds Don't Post" --> We need a Better Red Tracker
One thing I've noticed is that people often complain about Reds not commenting on things that Reds have actually commented on. The issue is that Reds don't -- and can't, and shouldn't -- post in every Lee Sin thread, for example. They should post in one Lee thread, and not have to copy-paste the same response into every single other Lee post; that's just a waste of their time, and I'd rather see them spend that same time responding to a Zed or Fizz thread.
I'm NOT saying that Rioters are doing this right now (they're not, they only responded to one Lee thread), but there WERE still Lee threads popping up after that response.
One area that this would be particularly nice in is Boards Feedback.
I've inhabited this board for a LONG time. Back in the day (before the old forums were closed), everybody who posted, had been a community member for a long time. So, we all knew what had been discussed and what hadn't. This meant that there was only a new thread every couple days, but each new thread was discussing something really new, that we hadn't thought of before. And we had Riot replies in probably 1/2 to 2/3 of our posts.
Nowadays, we're lucky to see Rioter replies in 1/10 posts. But what isn't obvious, is that 9/10 of the topics have already been discussed. That's part of the reason there are fewer Riot posts -- there's not much new feedback. But newcomers don't know this. How could they? We can't reasonably expect them to go back and read posts that are months old.
If we had a Red Tracker that was better-organized and more easily search-able, people could find responses that have already been given to posts they want to write.
Edit: just wanted to add that I know Red tracker improvements are on the radar. Reds: think of this as a 'Please consider this in the scope of your improvements' -type post.
