Let me explain it to you like this.....peace has been declared, but yet the generals still hate the other factions. (Redcoats hate Pirates, Bluecoats hate Redcoats, Pirates hate Bluecoats ect.) The Generals argue over who had the best soldiers/fighters, so to see who has the troops with the best skills, they hold competition's, the prize is the bragging rights, otherwise the Generals can say they have the best troops. Understand now?
Regarding the amount of brown: I don't have enough pieces in any other color, and I don't have any trans parent colors.
Thanks for the comments
