I don't play Dota 2, but I'd like to weigh in.
Once they've finished porting Dota 2 to Source 2, I hope they don't become too ambitious with any new features. I'll always have a place in my heart for Team Fortress 2, but after so many updates and additions, it's just not the same game anymore.
I don't know much about how the video game industry works, but the truth is evident. Valve is going to do things their own way, and complaining will not change that fact.
*EDIT*
Now that the video is up, I see that it was just me being impatient, however, I still find it strange that there wasn't much talk after the session ended.
I agree with marnamai. Don't let personal opinions adversely affect Valvetime's Reputation. The right people will see VVN for what it truly is.
