It's not onliners, it's not immaturity. In the APAC LCQ, the other teams were not good and EDG out aimed them. At Champs, it's becoming clear that EDG do not have a deep strat book even on their own map picks.
that's why this game is fresh. you will get aim-diffed by teams when they're on form so just having aim will not take you far like it can do in CS. you also need to have strats and good utility usage as plan B else you're getting rolled like EDG today
