EU Caster Feedback

During the casts of the EU professional games this week, there was a technical issue that I would like to see looked at. In a lot of the time that casters were talking, we could hear stadium feedback (a few milliseconds after the caster spoke, we could hear the words echo through the stadium at a lower volume). This isn't a huge issue to the average person, but I have a hearing disability which makes discerning details during white noise (such as background talking) very difficult, and I left watching the first day of the EU cast with a migraine. I watch both NA and EU LCS every week, and would like to be able to continue.

The cast from the end of the Day 1 was better than the beginning of the day, I'm not really sure why, maybe you guys realized it was going on. It started again in the beginning of Day 2. I would appreciate some audio engineer looking into this, I'm sure I'm not the only person that's at least a little bothered by this.

Thank you, Alroid
