This is something that was asked yesterday and Frank Fields (AKA RiotMirhi), on our lolesports content team responded pretty well to it.

Jatt shared this with me earlier, but unfortunately with our coverage plan, we didn't have room for it on the website. We have Group Previews coming in the next few days (Written by Emily Rand, Leah Jackson, Josh Augustine and myself). It would be sort of weird to have two Group A previews, but only one for Group B-D (although I hope Jatt does more, because I enjoyed reading it), since he hadn't decided to do all four groups at the time.
This type of coverage is excellent. I love it. Luckily his analysis in this post caters very well to the hardcore (Reddit) audience. Most of our coverage caters to casual audience (League client), but hopefully some of you still find it insightful.
Stay tuned for Emily's Group A Preview tomorrow and the others throughout the week.
I hope that clears it up. We really appreciate your feedback and the positive feedback around Jatt's articles have certainly opened quite a few eyes around the types of content esports fans want as well as the (positive) impact this type of content can have on our boards.
Here are the Group A and Group B preview articles mentioned.
