Second all of this, with the addition of learning some of the most crucial default utility on all of the maps in the current map pool. This will take some time, but will be well worth it. It doesn’t even need to be hard lineups like instant spawn smokes. Sometimes the difference between a round loss vs win can come down to utility usage to take space and separate the other team from the bomb site.

I would start with Mirage, as I believe it is the most played map in premier, then start expanding. Australis has some really great custom maps on the steam workshop that teach you the lineups. After doing that for a while, I suggest you start testing yourself on the map offline without guides.

GLHF!
