I was just thinking; would it be a good idea that as you level up in a certain skill set, say blade, then your technique slowly develops. Say for instance a character whom is not a high skill level does not hold the sword correctly or swings differently, slower and with less balance, things of that sort compared to a level 50 character in this skill set that has basically become a master and perfectionist in this category and strikes with upmost impeccable technique. It would be good to see this, agree? It would also be good that as you leveled up you become slightly faster, had quicker moves or more complex moves and become less predictable - not just swinging your sword around like it is nothing with the same old animation; that is what I hated about Oblivion. It would also be good to decipher what level or how skillful your opponent is. Get voting!
If they do modify this, which they won't, then I also hope stamina has more of an affect on fighting other than the amount of damage you deal but more of; how fast you are, damage dealt, the amount of balance you have, and things like this.
