Ahhh, c'mon, it's not that hard for Acads. Acads need to learn things the hard way at first, or else they would never cope with the things that you need in order to survive and be prosperous in the game. I mean, it is not that hard eventually and after you put some sense into it.
Acad attacking a Chuunin+ = Bad
Acad attacking another Acad/someone your level and rank = Good.
They need to learn the hard way, as everyone does to get things into their minds.
It's also their duties to read the FAQ, and if they don't, their carelessness is blamed on them. Also, with the new thing Neji has for the Academy students, in which they are forced to read, that should be enough...
