I dunno, it really doesn't take me all that long to kill a pack of mobs. I don't know about the first dungeon bc I did it with the trust system, but all of the dungeons after I've been massacring pretty quickly. Maybe people are undergeared or still adjusting to class changes? Maybe the mobs won't be that bad once we all know what we're doing and have better gear? Also, I extremely disagree that the dungeons are bad. I actually think they're far better designed than most dungeons that came out of Stormblood.
