Hmmm, not such a bad option thinks I.
I may have put maybe two tained units into chain
Limited to leather - not such a bad option ...
Well. Let me express my surprise when I tried to create my first trained unit - after resaerching leatherworking
Helmet - check +2
Braces - check +2
Breastplate +4 - Nope
Cloak - Nope
Greaves - +2 - Check
Still a great game
