Abilities of Skills as Majors:
Acrobatics - as a major you could do cool acrobatics moves like climb walls, leap off of them, dive from high heights into water, etc. Of course, on top of the abilty to already evade at level 50 like in OB, or water jump (rediculous IMHO) at level 100.
EXAMPLES
---Level 1-24: standard jumping
---Level 25-49: the abilty to attack/use magic while falling and improved sneak attack +(PLUS!!!)+ the ability to do arial attacks (ie leap on top of a target ala Assassin's Creed style, though maybe a NO insta-kill)
-Level 50-74: the ability to dodge +(PLUS!!!)+ the ability to climb walls, or something of this ilk
-Level 75-79: the ability to run-sneak +(PLUS!!!)+ the ability to vault/slide over/under objects
-Level 100: the ability to water jump +(PLUS!!!)+ the ability to dive from high places into water (to escape from being chased)
Abilities of Skills as Minors:
Acrobatics - as a minor you could jump. Plain and simple. Of course, the higher your level the more you can do, but would not get any serious bonus to the levels like if it was your major.
Let me know what you think of this revelation... or if it has been done before. But I hope it hasn't and haven't seen anything like this yet.
