Other way to gain garrison resources
Each level 2 or level 3 garrison has a Mine, (if you choose for it) a Lumbermill and (if you choose for it) a Barn.
I think it would be a lot better if the following changes were made to it:
Mine
Current situation:
The Foreman takes your collected Draenic Stone and creates Blackrock ore.
New situation:
The Foreman takes your collected Draenic Stone and create Garrison Bricks from it.
Lumbermill
Current situation:
You bring collected Timber to the Foreman and he creates Garrison resources from it.
New situation:
You bring collected Timber to the Foreman and he creates Garrison Planks from it.
Barn
Current situation:
You bring collected Caged Beast to the Foreman and he creates Sumptuous Fur, Raw Beast Hide, Savage Feast or Savage Blood from it.
New situation:
You bring collected Caged Beast to the Foreman and he creates Garrison Meat + one of Sumptuous Fur, Raw Beast Hide, Savage Feast or Savage Blood.
There will be a new NPC added to your garrison. The NPC will stand at the location where you gather the free garrison resources currently. The collected Garrison Bricks, Garrison Planks and Garrison Meat can be turned in to get Garrison Resources. 20 of each gives you 30 Garrison resources. The change of collect Apexis Crystals will still exist also. The free garrison resources will be removed.
