Hey, I get it! It sucks to be ignored, and if you feel ignored you should let Riot know. This is coming from a S1 Heimer main, so you can understand where I come from when I say this. Keep talking about it, because that is the only way they know it is still an issue.
That said, GD has been complaining for almost a year straight now due to 95% of serious discussion, some of which directly affects them as a community, has been done either on reddit or here on the Boards. They have been pretty vocal about it, so I'm not surprised someone lent an ear and posted something significant over there.
I realize this has been a complaint from EU since league began, but that is why they are creating the boards. It just takes time, and a good helping of patience.
At the end of the day, I get it. You feel let down again, and you aren't happy that it keeps happening. However, these boards are the direction that they have needed to take for a while in order to improve communication as a whole. This has been a pretty risky move for them too, as they kinda cut off communication from large swaths of their community in order to make it happen. Hopefully, the risk pays off, and not only EU, but other communities like Latin America and possibly eventually East Asia (if China ever relents on their censorship).
