The difference between a reasonable and unreasonable player in Party Finder?

[AmnesiaHaze]

A reasonable player will set up their party description in a manner befitting of their party.
An unreasonable player will complain on the forums about the way someone else set up their party finder description, instead of just not joining their party.

i dont know , threats of kicking or even blacklisting make me not join that party in the first place, i have no desire to play with people with such attitude no matter how good they are at completing the objective
