I love making complete sets so my characters look sensible. That said the weird thing is...
Everyone starts out making breeland armour and as we level up we only ever get automatic access to one developer chosen armour style. What would be much nicer is if I'm an elf, I make elven style armour by default. Dwarves make Dwarven armour and Humans make Human Armours.
Make the recipies multioutput, but give access to them based on faction rep.
For Example:
Tier 1 Armour. As a Dwarf I can make Dwarf Make Bronze Armour. Set it as multi-output and then once I gain enough faction rep with Bree allow me to make Bronze Armour, do something similar for the elf styles and we're all set (this could also be extended to tailoring which has even more issues due to having both Medium and Light Armours).

This has the benefit of:
1. Slightly reducing the number of recipes armour crafters have to find (which if you want to get full sets can be HARD, it took me 3 months to get the full set of Dwarf Make Heavy Iron)
2. Increasing the value of faction Rep
3. Increasing Armour Varieties available
4. Has great possibilities for End Game Armours
