How difficult is Freedom Unite / MHPG2 considered to be relative to the other games? Only played Tri before (not too far yet, 2nd lagi meeting), but after getting my Vita I've put in about 12 hours with FU.. Met no challenge until Khezu - this blind slime took away half of my health bar for every hit and survived what I felt was a very solid number of clean great sword hits. I got him but had to waste too many potions for my taste.
MHFU: Hard
MH3: Slightly less harder
The things that make those games hard are mostly not knowing what to do, monsters hitting relatively hard, and broken hitboxes.
And Khezu isn't that hard...it's basically just hitting it while not getting shocked. If you're getting shocked, you're doing it wrong. Very wrong. If you're getting hit by other stuff, get out of the way.
