Is there a hard limit of 4 of the first few dungeons?
My static group is me plus 4 mates, one of whom couldn't make it last week so we ran as a Light Party of 4 and completed the first 2 dungeons. This week, we go to re-run the dungeons and it wouldn't let us in with 5 people. I thought it would just 'promote' us to a full party, just with 5 people instead of 8, but the dungeon was just locked.
So it seems we can't actually level as a group of 5, is this true or did I just miss something that would allow me to change the type of party?
