What I mean are the skill perks that were in Oblivion, they were my favorite thing about leveling up a skill. The were some pretty interesting ones like the dodge/roll you get from gaining Journeyman Acrobatics skill, or the zoom function in archery from getting Journeyman in that skill. Unfortunately a lot of the skill perks were boring and bland, like the simplicity of Alchemy or Athletics' perks. The power attacks also weren't too cool considering they were all the same.
I was thinking that all skills should have some interesting perks, like with Mastery in Blade/Long Blade would let you dual wield two long one-handed blades (if dual wield is present) along with a new power attack.
-At Journeyman or Expert Alchemy skill you could create explosive flasks.
-At Expert Destruction Spells could have a random chance of inflicting a second effect, like fire spells having an extra DoT effect, frost spells having an extra slow effect, and shock spells having an extra paralysis effect.
-At Mastery in Sneak you could perform special assassination moves with daggers, and their success would be based on your level over your opponents level.
-At Journeyman Athletics you get the ability to sprint, which reduces fatigue.
Novice in anything should just give drawbacks, with Apprentice in skills would have no negative effects.
This would give a much greater end game feel of being a real master in a skill.
What skill perks would you include, or do you anticipate?
