Is it unreasonable to seek people at the part of a fight as you are?

It's your party finder, sure. But that's quite a disservice to anyone who's just getting home from work or school and wanna learn the fight. This is the exact same thing the JP playerbase was giving the NA players shit for.

Nah. Even JP has PF for certain parts of the fight.
It's not like he asks for people who've cleared the fight.
He just wants people in the same level of progression as him.
Though he might have better chances of opening a normal learning PF party if the 1st phase is as easy as he said.

The JP playerbase is naive about and doesn't understand the culture of the NA playerbase.

I'm pretty sure they're not naive about it. They already know about the terrible stuff associated with NA xD
Though the part about not understanding it when such behavior creates such a terrible community is probably true xD
