I actually found some uses for jumping
1. When monsters are running away on the field, makes catching them a lot quicker (yes you actually move faster on the world map if you jump).
2. The golden orb things that give you the miracle move, jumping in battle also lets you get to those things and catch them before they touch the ground.
But yea other than that it's pretty useless
That having to catch the babana tree monster thing was the most annoying quest ever. Took me 50 fecking tries and an hour and half of play time. Stupidly low capture rate.
