I'm going nuts, I know that either on this forum, the beta forum, or the US forum I read where someone claimed to have talked to the developers about the blue print drop rate, but i can't find it now. What I remember though was that the person claimed that the devs indicated that whatever formula they used to randomize blueprint drops recycled after a period of time. I personally notice that it seems like every 1.5 or 2 weeks there will be a day where i will get like 4 blueprints, the next day pick up 2, and then it will be slim pickens for awhile before it seems to 'reset'.
My question though is not where I read that post, but are blueprints drops specific to an individual player or is it more like an Easter egg hunt free-for-all. By Easter egg hunt, I mean do blueprints 'generate' in buildings just waiting for a player to Polish/Motivate and thus anyone Polishing/motivating that particular building could get the blueprint? I always thought, and the person's claim I mentioned above seemed to confirm, that blueprints drops were specific to individual players. If receiving a blueprint is a result of the Easter egg hunt scenario then it would seem there would be an incredibly small chance, but a chance that someone could get a blueprint with every polish/motivate.
This question of mine was brought on because a certain guild member of mine claims that we do not polish/motivate enough in the guild (his numbers are way off though as I know for a fact he is miscounting). Part of his 'evidence' is that he got 4 blueprints for great buildings he already has and those blueprints could have gone to other guild members. The only way those prints could have been procured by another guild member is the Easter-egg hunt type scenario. I tend to think blueprint drops are more specific to players and that whatever algorithm is in place to generate the drops does indeed recycle after a period of time.
I hope this ramble makes sense. Thank to all that respond with valuable input.
