Listened to the first ten minutes.
I think they are too closed minded. Like they dismiss the pick/ban phase as a bandaid which is a phrase that has always felt like a big buzzword to me. Call something a bandaid and that's your argument, you don't have to really look at why it positively influences the game.
I play a lot of DOTA 2 and I play on a casual-level team in a small time league. Actually had a league game about 9 hours ago. The pick and ban phase is a vital part of the game for reasons they do touch upon but don't give enough credit, IMO. And they also say that it's there to handle the fact that the game has too many characters. Sorry but too many? U wot? The game has a lot but characters but that is a GOOD thing. Variety is the spice of life and I doubt my interest in the game would be the same without the wide selection of characters available - the meta would be so stale. You have 10 characters in each and every game meaning approx 1/10th of the entire pool is picked and 1/10th is banned meaning that 2/5ths of the pool has been picked/banned nearly half. If you take away characters from that pool then you WILL find stale gameplay, the whole point of MOBA games is to have an ever evolving meta based around new strategies with the vast pool of characters.
I'm not saying that picks and bans is the absolute best way to handle things but in the context of MOBAs it most certainly is. Also that guy says he's done with all MOBAs except for HOTS which basically rules him out from talking about MOBAs in any serious discussion.
