There's quite a few Occupations in Agricola that elicit a traumatized shudder from hardened Agricola players. I'm thinking of cards like the Taster, which basically allows one player to be in a position BETTER than being starting player during any round of the game, for the low low cost of 1 food per round. I've heard that a lot of groups have physically removed the Taster from their set, rather than have to deal with the imbalance it creates.
Having said that, I've had very tight games both playing and playing against the Taster, and I completely crushed an inexperienced player who laid an early Taster in a 5-player game a few days ago, so I'm not TOO worried about "busted" cards. Even so...
Have any cards been played in one of your Agricola games that seemed to tip the balance too far in favour of one player, too quickly? In our group, we groan when we see the Field Watchman (such a no-brainer) and the Wet Nurse; cards whose value is just a little bit too transparent. What about your group?
Also, Minor Improvements tend to be a little bit better balanced on the whole (coming with costs and limitations as they do), but I'm sure some of them are a LOT better than others. Any suggestions? I'm never disappointed to have a plough of some kind among my opening seven...
