More 8 man dungeons?

[SkizzleAbernath]

Pretty much as the topic says. There seems to be a huge desire for 8 man dungeons that are not raids. Something similar to the main story roulette but not a main story dungeon with long cutscenes if you know what i mean.
Is there a reason for this not being a thing yet?
It gives us the chance to help more people and take along more people from our FCs/friendslist/LS so more people can get xp and do things together.

EDIT: Just to clarify since people are jumping to conclusions really fast, NO ONE WANTS LONG CUTSCNES THAT ARE UNSKIPPABLE. A cutscene in the beginning when you enter and one after the final boss is all thats needed.
