well when 1 clan cant defeat anothers by themselves and must rely on the common enemy to team wit them to beat them, that is when its time to call it quits for the one clan, if a clans gonna take on another, thats how it should go, u dont need to go bringin in other clans to defend u cuz ur the weakest link
What I meant by that is like say MysticShadows and Devil Wings (just as an example) we both are enemied by Dynasty. A long the way Dynasty highly annoys one of us to the point that Dynasty just has to die... That is the only way i could see an actual gangup. Otherwise, I see now power to be gained or loss. But then, I'm looking at this from an roleplaying perspective.
I just can't see any benefits of enemies teaming up outside of that reason cause there is nothing to be gained by it whether you're in a clan or not.
