Dungeons are being destroyed by hunts. Average wait times are over 30 mins to an hour at best on story mode dungeons now on my server even selecting all languages, I feel sorry for people who are leveling and trying to get story mode dungeons done my friend had a huge wait on titan normal for story progression. I've given up on animus books for now in the hope something will be done to improve this. At least my gathering and crafting is being leveled. To answer OP first run through the game dungeons are fun with story but then they're mainly tome grind or animus grind.
