Ok you can kill people and then heal them. What else? Nothing. It's doesn't make any sense that magic would replace the need for science unless you can do more. The thing is that they can do more, you just don't get to see it. TES keeps way to much knowledge of the series in the background, it's one of the only flaws of the lore in the games. No more random books that give little bits of information that usually doesn't relate to anything. They need to actually show that stuff.
Guess you havent been playing a mage much then, or read a lot of in-game books.
A lot of people happen to adore the books in TES, so I dont think wanting them out will help.
The uses of magic are myriad and extensive.
And so is the use of technology.
I actually always get a little depressed at people calling it a medieval game.
Its not medieval and has nothing to do with medieval.
Technology wise they are quite advanced and seem to be at the point we were just before the industrial revolution.
I just dont think one of those will ever happen, as magic takes care of a lot of the things technology is handy for, so there simply is no need for it.
