My race has the "master smiths" perk which is supposed to halve upgrade costs.
I am attempting to upgrade the armor of an unit. The unit's spear and shield are already up to date; five pieces of leather need to become light plate. The cost is 5 metal, 469 Gildar.
For comparison, the cost for rushing the same unit from scratch is 406 Gildar... that includes a horse, two belts, an amulet, a spear and a shield that the existing unit already has.
It makes no sense that the upgrade with the perk will cost most than producing the unit from scratch, especially when some of the gear is already up to date. If it's a bug, I hope it's fixed. If it is a design decision... well, I for one, wish trained units would get some love.
Here's some visual aids. You'll have to trust me that it is the same unit.
