The practice in Apex Legends is generally bad. Reason is I want to use it to test other Legends and practice aiming with other scopes. You are stuck with Lifeline no matter what which makes no sense. We cannot use other weapon attachments or scopes at all. If you want to get better, you have no choice but to practice in live matches and get randoms who might get mad at you.
If I could practice aiming with scopes in the tutorial mode or practice mode. I will slowly become much better at the game. And maybe become good enough to get my first 20 BOMB.
