WotC's Complete Scoundrel focused heavily on the skills a scoundrel uses to get what he wants, and by and large it was a Complete Warrior for skill monkeys. Far too often, however, players forget that even without the variety of skill tricks introduced in the book, skills are an incredibly useful tool in combat as long as you use a little ingenuity in their application.
(Note: Pathfinder did us the favor of jamming together several 3.x skills into a smaller list. The relative skill for you here is "Acrobatics", but today we'll primarily be focusing on the jumping aspect of that skill.)
Jumping has obvious benefits, such as not falling into a pool of lava or clearing that horrific thousand-foot drop into a pit of advanced dire ropers. This requires no imagination, and is not the sort of benefit you need to imagine when picking your skills. That sort of obstacle is easily cleared by anyone in the group having the required skill, a piton, and a rope.
Imagine the following scenario, however. It's still an easy one, but just walk with me and we'll get where we're going.
Imagine for a second that all that green muck is rough terrain. Your friend is at -6 HP and the enemy is nearly dead, but unless you can take him out he's all set up to coup de grace your ally. Now it doesn't take much of an imagination to create a solution here, but it bears mentioning that if you try to move through the muck to your friend you can reach him with clever use of diagonals and end up right at 30 feet of movement used. You could heal him, but he would still be the enemy's primary target.
- Battle Jump - Think "Dragoon" from the FF series, and land for double damage with a leap from above.
- Vault - If you're into actually wielding a lance or spear for the Dragoon flavor, this feat will make jumping over even huge enemies a much easier task.
- Leap Attack - This is actually one of the foundations of the ubercharger. Since Battle Jump makes the maneuver a charge, combining these two feats can actually create absolutely bone-shattering damage totals.
