Ehem, Stabbing monster while mounting them won't do a lot damage , however , what come after that is matter.

+ The back of the monster ( or in some case, head / horn ) can be destroyed easily with stabbing attack , plus the monster will be tripped and stay down for a lengthy of time.

+Next, if another player manage to stagger the monster while other is mounting him , the monster will switch to it staggered animation , which , unfortunately , will act just like when the hunter successfully finish the mounting mini game , and the monster will end up throwing the hunter and do the staggering animation instead , and everyone hate it because..

+In MH4, it is harder to trip the monster by aiming at the leg , they seem  have more resistance and the monster only stay down for a short time before get back to action , unlike the one suffered from jumping attack.
