Here's what I've been thinking lately:
One thing that I have not seen is explanations and analysis of strategy and decisions in matches. Especially in pro play.
Now an issue is the videos need to not be long and be simple so a wider audience would understand, which probably isnt easy to do when discussing "strategy". Now what I mean by "not long" is either abridged or a strategy in action with a few examples, not to do whole matches, people dont seem to have the attention span nowadays. If it gets popular slowly increase the length and complexity, training the audience.
So this is probably more of a "in theory sounds good" but "in practice is poop" idea. Also the amount of viewers for such content is probably highly questionable too. Btw if theres a channel in english that already does something similar point me to it.
