A suggestion for feedback threads made in GD.
I'm not sure how much control Riot has over forum tools, but I've got a thought as to how you could get more value out of a Riot made feedback polling thread.
Which would be one half a demonstration that Riot's hearing things, and one half an easier way to give feedback.
What if, whenever you make a thread like the Skarner or Rengar follow through thread, you created it in another forum first. Have nine placeholder posts to fill the first page. Leave them blank to begin with, then ask the public what they think.
As you get valid responses, you reset the upvote/downvote counter on one of the placeholders, paraphrase the most common complaint, and provide a number of quotes to people within the thread who make the complaint. Allow everyone to read the problem and vote on it. If they feel your paraphrasing doesn't adequately describe the problem, they could downvote, and if they agree with your paraphrasing and the problem they could upvote. No real response needed, just a demonstration that you understand what people are saying.
I figure this would allow you to see what problems people have with any given change, how many people have that problem, and it could well give the general populous confidence that you're listening to what they're saying.
