Ok, so I suggested before the start of this age to buff homes a little bit in the BE department so that it can actually provide a bonus.

Let's look at the math and see why homes are totally useless and pathetic and needed the buff in the first place.

1000 acres
Province A = 0% Homes 13333 Peasants (80% of Workers Needed for Max Efficiency)
Province B = 10% Homes 14133 Peasants (94.22% of Workers Needed for Max Efficiency)

Province A has a BE of 90%.
Province B has a BE of 97%.

Homes don't even make up the 10% loss from all other buildings.

So I suggest again, gives homes an additional bonus:

Increases your building efficiency by % * .5
