I would like to ask why Riot is ignoring Eune community.
No, don't say that they are not, just look at devtracker and it becomes obvious.
I'd also like to ask you to reply to this thread : http://eune.leagueoflegends.com/boar...d.php?t=565330
I'm not a community guy so I can only speak for myself and these thoughts are simply theories.
My guess is that the issue started with the majority of the Devs working in the Los Angeles office. They play mostly on the NA servers and as such as almost all rioters are players of league of legends before coming to riot, they are very used to logging onto the na forums already and have probably posted there in the past.
With that as a start my guess is we've run into a bit of cyclical problem. Less Reds post due to forums being less active, which in turn causes less people to post, which means Rioters looking for feedback on an issue find a lot less here than on the more populated forums, focus their efforts where they get the most feedback for their time and cycle continues and worsens. I don't have a great solution since pretty much all Red posting is done on people's free time at home (I'm writing this at 02:00 myself). I read these forums daily on my own time (same with EUW) but post less frequently due to the heavy time investment required to do so - I can generally read about 5-10 full threads, or skim dozens in the time it takes me to make a couple of posts.
I don't have a great solution unfortunately and it's not an easy problem to solve. It's something I know the EU Community team has been working on for a long time and it's something I've been working with them on as well when I have time. I can't give you an eta or honesty any more details beyond that but it's something we're not satisfied with either and you are justified in your frustration.
