I did over 400k exp in half a day, and it was really great, i don't see why exp should be lowered where there's no real content for a low lvl.

Plus, it's a good thing, because having a lot of R50 will help you greatly on your main class having a lot of sub skills.

Remember also, when Jobs will come out, there is no exp to lvl them, only quest.

And it isn't 1k/mobs, it's mostly 400~600 with a normal group, with a good group, you can reach 800~ and if you have a powerfull group, it's 1k/mobs. Atleast under R40, after you can be PL probably by some R50.
