Some issues for me when watching streams on hitbox. And also (do not take this personal) but I do not find the commentary very entertaining, it lacks enthusiasm, passion..it's just not entertaining to watch with a commentary that sounds like the commentator himself is not having a great time doing what he has decided to do!
Check iRacing commentators from the F1 championship thing, they have more passion for it which makes everything way more entertaining.
..you know, people like to have commentary that's entertaining. Doesn't matter what game it is or whatnot, Dota2 The International 5 commentators are great, so are CS:GO commentators in pro games..the list is endless!
