I do drug runners as my main source of income and i make up to 1 mil in around 6-8 hours of flying, never failing once or even taking damage during landing, I think its the best source of income and the easiest... Its perfect, it does not need a nerf or buff, all its needs is a good pilot and you'll earn bank. So i have a simple solution for you my friend, learn how to fly.
I think ive said everything that needs to be said, *flies away*
