boss exp

[a pinnapple]

i've been attackin the same boss for a few days now, skullcrusher ogre, and the exp is geting less and less. it started i was getting around 62 exp every successful att, then i went down one after a few attacks and then again. now i'm only getting 59 exp per win and i dont know why. it doesnt seem like a glitch but i don't see why it happens. if this is by design how low will it drop to?

As your user level goes up, the exp/hit goes down. It drops until your user level prevents you from attacking that boss at all (when you are 150-200 levels higher than the boss level).
