HUGE pacing issue around level 40

[aerolol]

Do you have the challenge log unlocked?
Are you doing your daily low level dungeon roulette? The exp bonus you get + the exp from killing dungeon mobs is enough for more than half a level, maybe even one full level up.
At level 41 you can start taking beast tribe quests which give some extra daily experience.

All these things didnt exist in 2.0, so the exp grind was even worse.
It's much easier now.

Pretty much this right here. My first 50 was before the challenge log itself and I managed to get there around the time I should have been lvl 45, in part because I would do the low roulette. It was as a Paladin which did make it easier to get in but my point is, it isn't quite that difficult to get to 50 even for a new player.

As well if you want to get other jobs to 50 you won't be able to rely on quests since you already did them, though it'll be a bit easier since you will have an auto +50% just from being lower leveled then your highest job.
