it would help if you could tell us which Race you play
since theres quite a few differences between them
For Humans (which I play)
Barracks train Footsoldiers
Stables train Knights
Shootingranges train Archery Units
As for Tactical Suggestions
well best is Experience
But as you already said you can look it up on the Merc Traders
different Towns have different Units
In the Shadow of the Black Cross. We Fullfill our Duty in your Name.
And Look forward to the Day we Return to your side Silvanos.
Watching over our Comrades as they Fullfill their Duty in your Name.
