Folks,

Not that I necessarily agree with the OP, but let's not forget a few things about the state of 2.0 at launch last year.

1) Dungeons were worth less exp.
2) No Low Level Roulette

During the OP's time during the first month, it was entirely possible to run out of quests to do getting your first class up to 50 if you didn't do every single FATE you crossed paths with. People always complained of the dry spell from 46-50 if I remember correctly, where the quest chains from Urianger every level only netted about half the exp to the next level and left you high and dry again, and it was FATEs or levequests or bust.

That being said, there is a simple solution for the OP, once that I rode from 2.1 to get all classes to 50 since launch (mostly. I am legacy, but my highest level prior to 2.0 was a level 19 lancer):

Low Level Dungeon Roulette.

Yes, the queue takes some long times to load for ranged DPS, especially if you're playing at off hours. But during that time, take your level 50 job and go do your six daily beastman quests. That alone should usually take up most of the time you would be spending in the low level dungeon queue.

And let's not exaggerate about the terribad groups that screw you over and waste your time. Yes, they happen, but they are rare unless you are the person who is making them fail. Through a few hundred levels of low level roulette, maybe 1 in 20 dungeons have enough failure in them to be a waste, and if only one person is screwing it all up, well, rarely does low level give you a dungeon higher than Haukke Manor - most can be tanked by DPS, or healed by THM (crossclass cure) or ACN, and you can easily deal with a derpy DPS, even if it might take a few more minutes.

Low Level Dungeon Roulette. Between the exp for monsters and the bonus XP at the end of the dungeon, it's like a level every day. Sure, you won't be able to max out all classes by the time your next 30 days is up, but you don't need all classes at 50 (unless you're a bit OCD like me) and if you do, it's a long term investment.
