I think that we can agree upon the fact that it sounds kind of silly that a Master Fletcher would increase the production of my library.
I agree.
But it SHOULD make your archers train faster, and better.
Also, with the master architect, I meant adding another Master Building, not a great specialist.
Some values I'm thinking of
Master Fletcher: +50% production of Archery units
Master Smith: +15% production, +15% military production (total of +30% military)
Master Rancher: +50% production of Mounted units
Master Outfitter: +20% Military production, +30% production of Recon units (total +50% recon)
Master Architect: +35% production, -35% military production (balances to no military prod. modifier.)
Some logic behind it:
A blacksmith obviously has uses, beyond making swords. He makes the padlocks to keep your library safe from thieves at night. He makes metal fences and window frames that all sorts of buildings need, etc. There would be hundreds of uses of metalworking in domestic production, so I feel that the smith should give a bonus to normal production, as well as a larger bonus to military production. ALL military production, not just melee units. Knights need armour as well, archers carry knives and wear light chainmail, assasins need specially crafted daggers, horsemen need spears, etc.
Similarly, the Master outfitter, should give a general bonus to military prod. and a larger bonus to recon units specifically. An outfitter makes clothes, tents for armies on the march, durable boots for soldiers of all kinds, thick gloves, cloaks, hoods, etc. Things that would be primary equipment of a recon unit, but are going to be used by any type of soldier in general.
Also, I still want a Master Shipwright and Master Enchanter.
