It would be overpowered if it to have 100 or 200 fragments per item, as suppose above. So it just matches the rest of the awards of this building. Everything is harmonious. Once they appear, these fragments will fall from everywhere. But I'm not sure it's worth taking up 24 squаres of precious space with them
WW, SoK and settlement time rewards taking only 15 fragments. It's just the GbG buildings that take 100-200 fragments. Approximately 1 one up per month sounds very reasonable. Maybe not the most sexy production but definitely something interestingly new for players still advancing through ages with a bunch of event buildings consuming one ups every time you age up.
So usually I am not complaining about event buildings, they are all interesting in some way. But this time it is really bad.
Comparing it to live server .
People - I have +408k people
Happiness - I have +625k
Supply boost - I get 11 Mio per day
Coins - I have 11.6G
Supply - I have 1,5G
FP - I get 900+, during GBG it is around 1400-1600 a day
Goods - I get 1120 SAV goods per day + plus goods from lower ages
Guild - I donate around 1100 goods a day
one-up fragment - got 40 of these and another 58 Reno Kits
So to call this building useless for players in a higher age would be an understatement
So, your point is just bragging and showing off about how amazingly well you've build an established city and pointing out that every event building should be good for end game players while your practical post-scares meaning practically limitless resources? I get your disappointment but just like real life, not always getting what you want from time to time is a good thing. Same with events. Perhaps there are guilds out there that lack the luxury of getting earlier guild goods and younger player's who don't show up on this forum who don't have a huge stock of Reno and one ups because they're not end game? Just saying there's more than just you and your high performance city.

Personally I'm noticing an increase of spoiled attitude: building must be better than previous, no longer just requiring fps but at least efficiency of a SoK 0,5fps/square (in good old days this was considered best fp efficiency, lol) and topping it off it must have att% so, I may can get it slightly easier on GBG to maximise my already huge harvests even while siege camps preventing ever reaching max buffed defenders. In short Inno could just release an 3x3 building with 4-5 fps and smacking on it 12% attack bonuses, every event (partly sarcasm).
Glad that Inno doesn't give us always our way with attack bonuses.
This building is clearly like Shinto temple an resource building and as an farmland it makes sense. For young cities It'll be great to get started and mid game players who don't have an establish city yet or an "att% buildings only" mindset. Also for those who don't fight often or even liking GbG in the first place. To me it's value would also increase with an military bonus but it'll become something like fps that'll be expected and taken for granted. In imho releasing a bunch of events that even lack any type of bonus would be a good thing to hopefully lessening the spoiled attitude. Since this teaches us not to taking bonuses on buildings for granted. Also those bonuses devalued some GBs as it's easier to get event buildings than raising those GBs for similar bonuses.
Personally I would cycle through it over the year:
Spring - defensive bonuses
Summer - offensive bonuses (pirates)
Fall - resource oriented (guild goods included)
Winter - fps orientated - no bonus
Side events through the year: choice: fps or goods or medals or guild goods, 1 of the side events may have a unique production like golden crops
Standard efficiency for above noted stuff with 1-2% extra for each 2-3 ages based off Bronze Age*. With some variation in resource efficiency: fps 0,4-0,6 / square as an example. Military bonus: 0,5 - 1,5 / square.
*example building is 4x3 gives 6% Bronze Age than in industrial age it'll give 12% (6 ages further/2=3, 3 x 1% = 3% more than Bronze Age. Bronze Age 6% + 3% more for Industrial Age = 9%). Efficiency in Industrial Age: 9% / 12 square = 0,75%/square. In SAV it would be 15% and 1,25%/square. Roughly efficiency of eagle mountain. This is naturally just an example
I feel like with such an cap power creep can be halted and better expectations can be established as we know what to expect. On top of that there's always an chance to get att% buildings from daily specials, but only this event offers any chance for one up kits a month through daily harvests.
