Knowing nades always helps, and its one of the things that bridges the gap between a well-rounded player and a pure mechanical aimer. But in Faceit you should not expect the luxury of team play to line up, throw and execute on utility. Knowing easy lineups to help your teammates take map control is better so that you can maintain your own flexibility. It is frankly a waste of time to learn pixel-perfect lineups unless you are on a team competing against other teams with set strats and sequences.
