no not really… twitch dropped their deal with OWL a lot because they saw the numbers were TOO BAD for what the league promised. twitch was actually pretty smart and blizzard greedy and took the youtube deal. LA arena was not sold out, they gave tickets away for free just to fill it up.
it probably would helped somehow, but the downfall started already on twitch in the early stages. it just got worse and more noticeable.
