It's been less than 2 months. Leveling isn't "slow" just because you haven't finished something that is supposed to take up your time for the next two years. You can do savage, treasure maps, hunting, rare fates, crafting and gathering, side quests, sightseeing, jumping puzzles and bicolor farming when you get bored of leveling dungeons. It's ok to save some leveling for when they release the new large scale content or deep dungeon. It's not like people play 21 jobs regularly, so they don't all need to be capped ASAP.
