I'm just going to jump on one thing you brought up because most of what you said is sound advice and wht OP is sorta looking for. With ''would you like to not be bad?" you are implying that someone who has it set up this way are bad at the game. I really wish people would stop going around and telling people they are bad because their keybinds are non existent or not to your preference. Does having keybinds help? Of course. Are they make or break? no. Not everyone is a mythic raider/pvper. If this is enough to have enjoyment of the game then fuck it. Do what you want.

I clicked my top row of skills. Fuck I haven't changed the default Q and E. I outperformed those with keybinds. I also got outperformed by others who clicked. There's a limit. Keybinds will take you so far. You still have to be good TO BE good. If you are downright terrible, keybinds aren't going to change that. They might make you less terrible but still terrible. People have skill caps. Keybinds won't take people past what they are capable of.
