Once you get past the initial level 1-10ish hurdle of finding mobs without a very narrow level range (not too low to not give decent xp, not too high to kill you), each level actually takes the same amount of time until level 30, assuming you kill blue con mobs. After that, level 30 and each 5th level after that is a hell level that takes around three times longer than a normal level, and after each 5th level (31, 36, etc.), the following 4 levels take around 10% longer than the previous batch of 5 levels. At 50 it goes berserk with even higher xp requirements.
So, just wanted to give you a little encouragement that the first 30 levels are actually fairly forgiving xp-wise, compared to the rest of the game at least.
