Well i think you hit the spot. Aussie cs used to be joke(no offence) and now they have 2 Good teams with some other that have potential. They basically become one of cs best regions in a matter of months.
OG didn't impress me personally, just a mess of everything you can think of regarding CS pro scene. Rather boring stack that I'm not sure how going to operate further on. Just put every leftover thing you had in the basket and call it a sensation.
