In my opinion, if two or three people just keep on posting in this topic, then this topic will get no where.
Next, do academy students really bother you in the fighting zones? If you encounter any distractions, and just feel annoyed of it, why do you move into another zone?
If the purpose of this feature request is to have more zones only for sannin, hokage, or even grand hokage I would have to say no.
The zones are RP though. Not an actual part of the game. If I recall, the zones were originally put there to give people a place to RP. I mean, rank doesn't always mean they are stronger. If that would work, I'd be a much better zones fighter.
In what way would it be better if rank does have an affect on the fighting zones?
A higher ranked would win a battle even if an academy student could be better, or more skilled at what to do, I don't see that as being fair at all.
