I think the status quo middle ground in DF is good - most people will let you watch the cutscenes, but they will go ahead and pull the bosses as they only require one healer/tank, if that. You get to watch the cutscenes, and the rouletters get through the dungeon in a timely manner.

Now if you want the cutscenes AND the bosses, you're probably gonna want to reach out to your FC or PF for that. The same goes for those who want a full speed run. Nobody on either side of the debate is wrong, but rather SE was wrong for putting the cutscenes in those dungeons, a mistake they have since learned from.

OP getting kicked was unnecessary - with proper CDs those fights don't require healers at synced gear levels.
