My personal feeling as a crafter and gather with all of them 50 (BTN was my first 50) is make the main story a requirement. Will it compleatly keep out bots no but it will help a lot. I much prefer having to finish the story to help rid my competition against bots. If you are truly a crafter gatherer then you should want to keep out those bots. Players only have to do the story once but they would have to for each character bot. Please SE don't give them an inch.
