I have enjoyed pretty much every tier 1 VAL tournament's analyst desk and casters. They don't put on a huge act, but they also keep an air of professionalism and ensure every member of the talent team gets their word in edgewise. (May be occasional exceptions of course, but this seems to be the general trend) And for international tournaments, they get folks from all around the world who have experience with different regions.
I spent 5 minutes watching the CS PGL Major's analyst desk and it was almost unwatchable. An absolute mess of people interrupting others (mostly Thorin and Richard Lewis tbh)
How does a game's biggest tournament in two years have two people on it that don't understand the concept of self-moderating on an analyst desk? Including the guy who's supposed to be the damn host (aka the moderator)? Can you imagine working hard to get yourself to a recognizable professional level as a an analyst in esports only to have these two old problematic men interrupting your segments and making you look bad because they're that self-centered and impatient?
Gotta give it to Riot, they do a much better job of hiring talent that actually know how to present the product in an enjoyable, yet professional manner, and in a way that doesn't detract from the content. Thank heavens.
