Not a fan. I don't like it when the game mucks around with my character for reasons outside of diseases and debilitating affects. This just runs into too much maintenance and upkeep to keep my character in top form. It detracts from actually playing the game when I have to worry about my stats degrading for whatever arbitrary reason.
This is one of those things that sounds cool because "yeah realism!", but makes for a absolutely dreadful experience. This wasn't a big problem in earlier games. The actions we could preform were very limited, and Fatigue usually last you a long ways before running out of puff. Combat wasn't particularly engaging, so you had to do something to keep from preforming perfectly at all times.
The newer games though, especially Skyrim? Running out of Stamina is, no matter what, going to happen. We have power attacks, sprinting, blocking, potentially dodging and parrying...all incredibly useful things you might want to be able to do, but with only a limited Stamina pool to dip into. Having to worry about your attack power just isn't needed, because without enough Stamina to begin with, your character is effectively crippled as it is already. Your guards will break, parry attempts will fail, you can't dodge, you won't be able to sprint away from danger, you can't use a power attack to knock your opponent away from you. I can't tell you the number of times running out of stamina was the death of me in Skyrim. This is one of those things where you really don't need another penalty for running out, because running out is already a monstrously bad thing to have happen to you.
Not entirely sure Short-Blade is needed. It would be okay to have back in, but...a single Blade skill could easily cover daggers on its own within a Tree, and Short-Blade doesn't have enough content to match any other tree on its own.
Eh. Frankly, I'd ditch Luck as an Attribute in TES. Haven't been able to think of a good way in order to make it work, and since the TES model of Attributes is not static...well, I don't see how raising it would end well within a leveling system. Also, Willpower needs to be retained. Its a key component of both the universe and actual spellcraft, so Wisdom doesn't cut it. I'd add in a Awareness Attribute, personally. TES doesn't have any form of observation based abilities, and I think something like that would actually function better here then it would in Fallout.
Oh, and Strength checks on arms and armor? No thanks, those never been implemented well in anything. My little Bosmer should still be able to preform with heavy equipment, even if it bogs them down more then stronger characters.
