Ya once again, I think that having to learn learn every fighting combo after doing a quest from some trainer just to learn how to slash your sword is a bit to much. It crosses that line from "immersive" into "This is freaking [censored]! Why do I have to do 5,000 different things and this old guys laundry, which takes forever because I'm at a low azz level, just so I can learn how to swing my arm twice in a row!?".
You get where I'm going with this.
But still interesting idea though. :tops:
Why do you have to do 5k things for someone? It could be just as easy as finding the guy with the fighting style and paying him to teach you how to fight a different way, but if you aren't high enough level you'd have to apprentice him until he lets you buy it.
IMO it should be more of a cosmetic change, the weapon swing animations got old after 50 slashes in oblivion.
