I've read about cases where someone gets enough bp to finish the story, and then the dailies start selecting missions requiring the 1184 bp amout. Even though the story only requires 1100 to finish. Leaving them in a situation where they're short the means to get daily rewards to help them continue to increase their bp.
Perhaps the story quest that triggers the bp locked dailes should require the same bp lock of those dalies to progress.
Man I hope not, I just got to nex helio last night and got wiped with the floor during his second phase. I'd hate to be stuck progressing after killing this pain in the #&$
