Suggestion: A setting to switch walking/attacking function between Left and Right Mouse Button

Me, and a lot of other players are more custom to spamming Left Mouse Button when doing things in games, League has the reverse, you press the Right Mouse Button, and that really bothers me. So here's my suggestion to improve the game for me and million others. Add a switch in the game settings to switch the walking and attacking key between Left and Right Mouse Button, or just make those two keys changeable in the Keybinds' settings.
