The experience points ("EXP") required to attain the next level ("Next EXP") has been calculated to its necessity each time the level cap was raised, considering the influences that each of the raised levels has onto the world of Vana'diel. However, time has passed since the initial lift of the level-50 cap, and the final cap of 75 has been in place. Now that players are becoming more comfortable with merit points, the new way to enhance their characters, we believe it's time to reconsider such influences, and that the current Next EXP be changed.
Currently, variety of missions, quests, and BC battles are being provided with the wide range of targeted levels, and the influences of each levels are becoming smaller than ever. Therefore, the "slope" of the Next EXP that is drastically raised after reaching level 51 will be "smoothed," thus reducing the large amout of Next EXP. (Next EXP for 50 and lower will stay the same.)
The following factors will be affected by this change:
- EXP loss when KO'ed
- In case the currently accumulated EXP exceeds the new Next EXP
For level 25 and over, EXP lost when KO'ed is calculated as 8% of the Next EXP, with the maximum of 2,400. Accordingly, because of this change that reduces Next EXP, EXP lost due to KO will also be reduced in many level ranges.
If the currently accumulated EXP exceeds the new Next EXP, it will be converted to Next EXP - 1 (in other words, levels with 1 EXP). Therefore, you will be able to level up as soon as the update is complete.
Further details such as by how much Next EXP will be reduced will be announced on the day of the update.

now, 2 important points to go over;
1. "the 'slope' of the Next EXP that is drastically raised after reaching level 51 will be 'smoothed,'"
english site completely omits this line. this somewhat reflects what Tythera provided, but my guess is that the slope will be even more "flat."
2. EXP loss when KO'ed
in english page, it's written as if the lost EXP would be calculated differently after the update, but looking at my translation, u know that's not true. lost EXP is already calculated as 8% of the Next EXP after 25, and its max is already 2,400. what's affected, is the amount of lost EXP due of the reduced Next EXP, because it's based on it.
hope this helps.
