@edeba - add to those Blacksmiths and Farmers also the roads. For ex. 5 WS lvl.1 = 20 squares but without roads. With roads, would be at least 25 squares (depending where they are squeezed).
If you consider land-time requirements for BS, farmers, statues and necklaces, and convert to how many squares for 24 hours you get the following:
Statues, 2(t1)x (2x1 size) for 2 days = 8 square days
Necklaces 3(t1)x (2x1 size) for 1 day = 6 square days
Blacksmiths 5(ws)x (2x2 size) for1 day = 20 square days
Farmers 10(ws)x (2x2 size) for 3/8th day = 15 square days.
The blacksmiths and farmers take up way more resources than the statues or necklaces.
My suggest would weight these 4 badges very similar:
Blacksmith 2(ws) x (2x2 size) for 1 day = 8 square days
Farmer 5(ws) x (2x2 size) for 3/8 day = 7.5 square days
Interesting debate, now I am curious as to how size would actually change, but I am doing to calculate for if you have cleared space and aren't just fitting them in because of existing oddball spaces.
So to make a statue you need one road square between 2 t1, so instead of 4 squares/day it is 5 squares per day for 10 square days.
Necklaces need 3 t1 so to make 2 necklaces you need 6 t1 with 3 squares of roads down the middle for 15 squares, so for 1 it would be 7.5 square days.
The existing blacksmith, say making 2, 5 ws on either side of a road need 9 road squares, if you were making 4 you'd 19, not 18, and making 6 you'd need 29, so round 10 for 2 which is more representative for playing a strong FA. So that would be 50 squares for 2, and 25 for 1.
Statues with roads - 10 square days
Necklace with roads - 7.5 square days
BS with roads - 25 square days
Farmer with roads - 19 square days
With my suggestions
Blacksmith with roads requiring 2 workshops - 10 square days
farmer with roads requiring 2 workshops - 9.5 square days.
The ratios aren't exact, but each badge is pretty close to the same relative requirement as per my original calculation.
