Well i guess most of you havent realized that you can get resources after battle, not only money and rep.
Keep in mind thats only at NPC zone. (and maybe also when attacking other players - havent done that yet)
So how to get the resources:
After the battle is over:
1)Click on your army
2) Select Load
3) select how much you can
4) Click Confirm
If you have many rounds of the battle - most likly you loose if you have more than 1 round
After the 1st you can also get the resources and then click transfer back to home.
