Stories that focus on the individual should never require parties.

We talking about story line. There is no LOOT.

for edit : again, we aren't talking of scaling content for endgame, but story. Don't be an ass pls

You said

-people think "why i should do this in gropu while can be soloed by everyone ?"

The Answer is loot

Holy crap cakes... Like nails on a chalkboard...

Plain and Simple

Want Loot, must have 8 people
Want Story, can have 1-8 people.

You have already seen people will happily do Ifrit several thousand times for Loot, thus requiring 8 people.

Keep having to do fancy posts to try drill some common sense through.
