Before it was a bad pop+culture building (the phoenix cult at day 3 is better (better pop, teleport, no road, no need arti)), the sentient prod was virtually nothing and the effect is nothing for most of advanced player (a converter of 1 food to 14 PC every 2/4 days if you do not forget) .... now .... it is not so bad but it is a mixed usage building for a very high cost price to obtain.
Hope AW sentient boost applied to this building, if not ...
On the same time, a lot of user will have only 6 artefacts, + FA => level 9 only
I do some math for amuni :
Metal Factory 24 => 4x5, need 4252 pop & 1203 culture, produce 350 metal/3h, 350 sentient/3h need 1930 metal.
Hyp for me, with standard building, we can do 163.46 pop/case & 500 culture/case.
Hyp : to convert production from 3h to day : x 6.83 (9+5x3h)
The base production : 350/(4*5+4252/163.56+1203/500+4/2) = 6.94/case/3h (the 4/2 => 2 roads, optimal road on the small side with building on the other side).
If we produce 6.94/3h base sentient, we need 6.94*1930/350 metal = 38.27/3h, to produce we need 38.27/(1+700%+0.5)/6.94 = 0.65 case (0.5 = montains hall).
Thus to produce 55.52 boosted sentient/3h (6.94*(1+700%)) we need 1.65 case => we produce 33.65 boosted sentient/3h/case
=> 230 sentient/day/case (33.65*6.83)
The EVO building : 1105 pop, 2210 culture, 12300 sentient/2days
=> 1105/163.46+2210/500+12300/2/230 => 38 cases
The building takes 16 cases + 2 road. Hope that AW bonus applied to the sentient production of the EVO building.
Evo gives gold (lol), supply (+/- 0.5%/day) (on the other side, factories need supplies), 1 PC/day and the special effect.
On the other side, most people buff the sentient manufacture (when progress, not at the end), production x1.5+ for 13h+.
Do you see any great error ? An improvement can be to taken into account supply/case/day but i think it is second order.
