Keybinds for new PC gamer

As someone who is fairly new to PC gaming, I find it difficult sometimes to use the default keybinds. It breaks my brain when trying to hit certain keys. As of now, I am using Q and E for 1 and 2 on every character. I have yet to play all the characters but for Apollo at least, I have his 3 binded to right click. Melee and reload are on the two buttons I have on my mouse. My active abilities are R, Z, X, and C.

What are your keybinds/what suggestions would you give me?

Thanks!
