The XP curve is too slow in my opinion, past rank 20. Considering that, in this game, reaching top rank in one discipline is nowhere near maxing your character out, levels should take less time than other MMOs to get, not more. I think reducing the cooldown time on leves from the currently arbitrary 36 hours to 24 hours so you can get a daily routine in would help, but they need to reduce the exp curve past level 20 as well. All players, casual and hardcore, should be encouraged to get into endgame content because that is the real long-term appeal of an MMO, and extending the grind to take an eternity doesn't help this goal.

I'm not saying it should be Guild Wars style where you can get to max level in a couple days, but 3+ months of doing all these leves (which including crafting leves can take hours at a time) to get max rank in one of eighteen classes in a game that empowers people with multiple max-rank classes is ludicrous. Something I appreciate in most other MMOs is that if I put in a solid day of grind, no matter where I am on the xp curve I can probably get at least one level, so it feels like I accomplished something. According to the xp values posted on this page, later in the curve you might get 10% of a level every 2 days if you use an exploit in the system, which is less like a game and more like the daily grind at work--long hours of repetition for very little visible reward. Where's the fun in that?
