Well, as you know, MH has some disadvantages. What are the disadvantages that you want to fix?
Mine's Just..... add some underwater fights in MHP3 and instead of saying "returning to village in 20sec./1min.", it will say "supplies delivered" and on the supply box should be a Paw Pass Ticket. This is good for carving Lao's parts. You can carve ALL the parts and you can freely kill the Iopreys that are in Area 6.
