do i have too.. i can't find it...

*edit*
found it :D now that i look at it its not very well explained except for the announce things..

i think it would be a better war system if there were 2 gates at both ends of the field then when one village breaks down the village gate then the only shinobi left is the kage and sanin of the village (better make some good sanin boys and girls) then if the kage and sanin die then the village who broke down the gate wins. all people at the start of the war are anyone who joins (kage and sanin wait until one of the gates has been knocked down then they can fight)

announcment like this:

The village hidden in the leaf is under attack by mist! All shinobi defend the village! (shows up only for the villages that are part of the war and changes accordingly for each village)

wining/losing like this:

half winning:

Your village have broken down the village hidden in the mist's gate, prepare to stop the villages last defence! (shows up for the village who broke down the enemy's gate first)

half losing:

Your gate has been knocked down, send out the hokage and sanin to protect the village! (shows up for the village who had their gate knocked down first)

winning:

Your village has defeated the village hidden in mist's kage and sanin, you have won the war against the village hidden in the mist! (shows up for winning village)

losing:

The kage and sanin of your village have been defeated in battle, your village has lost the war against the village hidden in the mist! (shows up for losing village)

half win/loss:

Your village has had its gates knocked down, but your kage and sanin have succesfully saved your village! (shows up for the village that had their gate knocked down first, but their kage and sanin have succesfully saved the village)

half win/loss:

Your village has succesfully knocked down the opposing village's gate, but the opposing village's kage and sanin have saved their village! (shows up for the village who first knocked down the opposing village's gate, but then lost to their kage and sanin)

*note*
this will solve the problem of kages such as kaz (you won't know him unless you played NC in v3ish) just being able to kill everyone from the very start and make the wars more interesting for the weaker people who would be somewhat evenly matched. You also don't have to go the war since the join war tab should still be there
