limiting clothing to village is a good idea because every village will be more unique.
And the fact that we can't see the name of other ninjas before targeting them will make the gameplay harder and exciting because it will be very confusing to recognize our allies during raid, so a specific clothes for every village will help to know who is with us.
And if missing ninjas can wear the clothes of both villages, it will be perfect because we will be able to know their sides, or they will be able to spy for a village (without the creation of an alt) So the RP will be better.
And the best thing about this "future" update is the mask. The ninja will not be able to see our name before targeting us, and when he will target us, he will see a mask. He will not know if he must attack or not until he see our clothes. Of course, we can have clothes of none of the both village so it will be confusing for players. And they will eventually finish to attack their allies.
The best way to use this "future" update is to add MORE WAR ZONES
With many war zone, it will start to become a mind game haha
Example with the update:
*Dona is walking in a war zone and he is looking for kills to have a higher bounty*
Dona: Oh shit! A ninja without a specific clothe of my village! I hope that he is not an ennemy.
*click on the ninja, and the name appear*
Dona: Oh he is a sand ninja i will let him alive
Example with the update 2:
*Dona is walking in a war zone and he is looking for kills to have a higher bounty*
Dona: Oh shit! A ninja without a specific clothe of my village! I hope that he is not an ennemy.
*Attack the ninja without clicking on him and he dies in one shot*
Dona: Oh no, it was a sand newbie...
*Dona has one strike, and the sand newbie don't know who killed him"
Example without this update:
*Dona is walking in a war zone and he is looking for kills to have a higher bounty*
Dona: Oh! A sand ninja

Like you can see, Dona had to do more actions with this update, if he does this same actions every time, he will start to be annoyed and he will eventually attack his own ninjas without knowing it
In conclusion, It is good for RP and gameplay BUT it can be better with more war zones.
