I know it sounds like Madness, but often people forget that there is a % bonus to EXP in Lineage II, been so for quite a long time, during your first hours of playing per day. For people who only play for a few hours, this pretty much can turn the 10x EXP rate on Lineage II into 30x.
Which sadly means they level up dramatically quicker than if it was just a 10x EXP server.
I mean even though its just 10x I'm already past level 40, which is pretty fast considering the fact I barely played so far.
My main disapointment with this being, is well you level much faster than the server indicates, but at the same time loot/drops/adena are down tot he level of a 10x rate, but with 30x exp for those who only play maybe an hour at a time. It kind sucks really.
