I think about the budgeting has something to do with it and likely Valve gave that bare minimum and PGL set it up the way they've handled the budget. But let's still give it the benefit of the doubt since there will still be one final blow next week for the semis and finals.
As for those dramas about that we've seen, I think one co-owner or part of Fnatic has officially filed a complaint against it because of the admission of some players that they can hear the casters words like what runes the players taken in-game and those stuff so, let's leave it there.
Budget is a great excuse to dodge their responsibility for the failure to anticipant the sound leak. Like come on, just put some staff in, play some Dota2 games with their headset, turn on the arena's sound system and roar to the mic to see if staff can still hear the sound. How hard can it be? Or are you telling me they know about potential problems arising but because of 'much budget' so no decent headset or some piece of glass to make a soundproof booth? Irresponsibility.
It's not just all about the headset, a soundproof is still better and preferred just like last TI. But we don't know what will be the look of the next stage for the finals. Maybe PGL will do better on that.
And while we're waiting for some games in the coming days, March is out of T1 as coach, Xepher posted on his Twitter that he's now looking for a team and as well as Kuku, looking for new opportunities posted on his Facebook page.
