Question about Lionheart Castle Monster Experience

2.5x XD I may be wrong but it seems to effect the party bonus exp as well. I've seen pictures of people in a 6 person party getting about 32k on the mob kill then 60k+ on the party exp.0.o

Edit: Was wrong on the exp part but heres a picture from the level up thread that shows that I mean:

Any idea if he got majority exp or just leeched/minority exp?
