I don't think SKT went out of control, was aHQ that forced the plays to take themselves control and SKT couldn't do anything else except try to do their best in the situation aHQ forced them into until they could react or AHQ allowed them to react
SKT in the single game is not unbeatable, that's for sure, but I still see them as heavy favourites against any team
I am interested to see the semifinals as I think OG has decent chances to take 1 game off of them as they do less bad calls than aHQ and if they can get in an advantage situation similar to ahQ in game 3 they could be able to close the game and extend the series
