well, hard one ... MSL is known for being a very tactical ingameleader, and it obviously really has worked out in the past ... Recently he has been fragging aswell, where gla1ve has been struggling to get kills.
Probably not. Astralis is mostly about the individual performance of the players. MSL is a master tactician but he is not very good individually. But gla1ve has some really good tactics and can outperform most IGLs fragging wise IMO
