I just thought of a really cool idea and i thought i'd share it with you.

Currently all guilds get along like chums, no large scale fighting between them or anything.

How about guilds can declare war on other ones?
The things i would have it do:
1. Remove freindly fire from players in the same nation, allowing large scale combat without any duels etc
2. Count the number of enemy guild players killed, and when say 10X the number of guild players has been killed that guild loses.
3. <optional> If the guild loses then it either loses 80% of it's credit bank <posted about also>, or if it's a slauter would be disbanded.

I think this would really add to the game, but i know the details need to be ironed out
