Why do people expect a team that has played for less than a month together to be beating Mousesports with a fantastic stand-in? Mouz have their core 4 players who all know each other, they just let NaTo go off and do his thing as Karrigan said. OG players have to get to know each other completely. Either way, this was a great first run for OG, I see a lot of potential behind this team.
I do not remember ever seeing a new team in their 1st lan to do that well as they did.
It is soon, but once they can apply more defaults, and get better at communication and coherency, they can beat anyone if they continue fragging like that.
