My first alliance raid was Void Ark back when it was new. I wasnt paying attention, and blindly hit greed for both drops from the first boss. I won a pair of dragoon boots(6 years later, i still havent even UNLOCKED the class - so obviously not something that benefited me), and subsequently realized i could no longer win a piece for my BLM that week. I never made that mistake again. Oh wait, yes i did. In my first run of Raba. And MAYBE my first run of Factory. This was the first expansion that i know for a fact that i didnt accidently roll on a piece i didnt want my first run.
