hidan' used to be a very good gnw ninja but he's really lost popularity.

the main problem with hidan nowadays are ninjas that remove buffs and shields. kushina, shisui and madara are common in gnw now. they can easily remove your buffs and control your hidan.

the other problem is that a chaosed hidan still does massive damage...to your own team.and if you don't have a way to clear that chaos, you're going to be the dead ones instead.
