In the Before Time, we didn't need to pass quite as many hard checkpoints - Limit Break quests, mission quests, zone unlocks, etc. - to get caught up with the rest of the game veterans. But the checkpoints were a Hell of a lot more difficult because of the lower level cap, and leveling was also an incredibly-large time investment.
At least, now, when you're running around with that shopping list of prerequisites, the scenery is changing. Compare that to hundreds of hours of attacking the same pink birds over and over again. Assuming you could get a party invite in the first place.
