Ya, the boards are a brutal place man. I try to keep an open mind about things, 100% Slythion approved method of preventing tilt. Besides, very rarely is 1 opinion/preference 100% correct, there's always room to improve a point of view.
I think DQ is Riot's way of trying to make it more "sport-like" in the sense that it's promoting teamwork with other aspects of the game. Whether or not it's the right idea or if they are going about it the right way is for another conversation, but I think it's their plan to make it more of a "sport".
One of the main reason League is such a time-consuming sport to train for is that it's 95% mentality, decision making, and situation awareness with only about 5% actually execution of these decisions. Training/maintaining the mind at such a high caliber is much more difficult than doing so for the body
There's also the mission to make E-sports a respected sport along with traditional sports. Riot has done a lot in this field, especially the past year or so, heavily promoting E-sports to colleges and other organizations targetted to that age-group. Hell, you can get full-ride scholarships to many popular colleges for E-sport/League related teams, which I think is amazing :D
