They never give this info, for any aspect of the game. Not for major events, not for FAs, not for guest race costs. Not sure why you think you're entitled to that here. Everyone is up against the same constraints of doing the research, communicating with members, and picking a strategy.Some formal guidelines and actual documentation about the event from the dev team ought to be made available, indicating if you have X active fellows, with Y workshops and Z factories, this is what you can reasonably accomplish with actual people in a given time frame.
Until larger fellowships exploit it. If this were like tournaments where any FS can get the prizes for the 10 chests if they put in the work, exploitation might be less of an issue. With the mechanics in the FA, only 3 FS can get the top rewards for this event, no matter how much work any FS puts in. So, until that is corrected, it would be foolish to put in a mechanic where stockpiling badges for future FA's is possible. I don't mind skewing the game a bit for the big diamond players as they make it possible for me to play at a reduced rate (or free if I wasn't so impatient, lol!). Stockpiling badges for the next FA wouldn't change anything except they'd have to spend less money on diamonds next time. Not really a good business model there...This structure (starting over from zero each time) actually works against mid / small research progression or sized fellowships.
It also works against people building huge stockpiles of badges on push accounts during one FA, then moving into the primary FS just before the next adventure starts so they can use their push badges to improve the position of the other players.This structure (starting over from zero each time) actually works against mid / small research progression or sized fellowships.
That's unfortunate, but if you are aggravated by people pointing out the flaws in your suggestions, it's probably for the best.I won't be posting any more .. suggestions, thoughts, criticism, or assistance.
