Crafting and Gathering could be for you, from the way you describe your situation. But only if you don't Craft or Gather any of the end-game stuff. The Red Scrips system is basically the DoW/M Tomestone system, but for Crafting and Gathering, and it is anything but a casual friendly system. In your limited time, it's highly unlikely you'd manage to cap every week, which means you'd probably want to forgo the Red Scrip system entirely, leaving you constantly a tier or two behind on crafting/gathering potential.

That said, SE has said they'll be easing the requirements for Red Scrips this week, so... Maybe after the hotfix it'll look better for you. Still, I'd go into this expecting to be unable to craft or gather the best of the best, just so you don't get your hopes up and crashed.
