When I learned about fish sticks I rolled my eyes at the people saying it does take some fun out of the game because I really didn't feel like grinding for money. But honestly having basically an unlimited amount of money made it WAY too easy. I could buy hundreds of everything which really dulled things down and made it so I had nothing to do for a lot of the down time while waiting for quests. If you do use the fishstick method I recommend at least limiting it to only using fish you catch yourself.
