Well the reason why the point and click smokes are important is because of how much faster the pace on Fracture is. Also the big thing about three smokes is that Brim can shut down all the important chokes when executing on one of the sites unlike the other controllers. There is a reason why Astra isn't used by any team on Fracture and why BBL eventually went back to using Brimstone after having a terrible record while playing Astra.
