How to improve apex

I think you misunderstood me. I was not asking for skilled matchmaking. What I mean by having time to work with new characters was an option to use them in training mode. For instance I main Bangalore. But Itd be great if I could use Pathfinder in training mode so I could practice and get comfortable with him rather than just joining in a game with him and not helping my team as much as I would with bangalire. With his grapple there's a lot of movements that take time to get comfortable with. For instance you have to know what his max distance is for hitting walls with the grapple is, when you catch you have to jump and turn near but not 90 degrees to swing out and strafe to move around objects. I just want to be able to do this in training so I can get comfortable with it, rather than messing up in a game and getting killed because I over shoot a roof and now my team is 3v2. I don't claim to be the best apex player or even close, but I'd like to be able to get comfortable with characters with them on my own time rather than having to compete and practice at the same time
