Improved Formation Infrastructure

I understand why the developers want the Formation Infrastructure to provide less cost to Unit production, but first of all, it does not feel enticing enough to build them, only to buy them with money, because with the time invested in producing the barracks, one can produce 4 units. Second of all, it does not provide adequate experience to the units, which would actually be a more realistic approach. There should be at least some experience added to the creation of units in a city with Barracks, Tourney Fields and Military Academy.

Right now, Barracks provides -10% Industry Cost on unit.
Tourney Fields provide -15% Industry Cost on unit.
Military School provide - -20% Industry Cost on Unit.

To be more interesting and slightly more realistic, they should provide more than just those cost reductions, for example:

Barracks could provide -5% Industry Cost on unit and 3 Experience on creation per Garrison on City or Outpost.

Tourney Fields could provide -10% Industry Cost on unit and 1 Culture per Horses Deposit on City or Outpost.
Military School could provide -15% Industry Cost on unit, 25 Experience on Unit creation.

I don't know, I just like flavor in games.
