Would love to see more 8-man dungeons outside of coil and story mode. This could open the possibility for (gasp!) support jobs to possible be included in the party, which I know is likely a pipe dream seeing that yoship has mentioned a number of times that he wants to stick strictly to the holy trinity of jobs. But a man can dream, no?

Also would like to see dungeons with more mechanics in them aside from run through, clear trash asap, then kill however many bosses (3 or so) that are strewn throughout the dungeon.
