Dude, if your sword only dealt 30 damage in Oblivion, you need to go enchant it. Because of the way weaknesses stack exponentially in Oblivion, you can easily make an enchanted dagger that will take down anything in the game at maximum level and difficulty in five or six hits. The problem with level scaling in Oblivion and Skyrim is typically that the game gets too easy at higher levels, not too hard.
I used umbra, the best sword in the game damage -wise. I wasnt into exploiting back then either.
Not necessarily. There are lots of simple and easy things they could do but don't, like make toggles to turn off sneak corsshair, compass, auto health regen, etc. I think it is more something the Bethesda just cannot be bothered with because it would distract them from designing more cool looking kill cams.
I think the real reason they don't worry about this stuff is that they are focused on the bottom line aiming at the casual gamer who would never notice more options in the "Options" menu. Bethesda expects that their games will be fixed by the modding community for the serious roleplayer.
I think that is shortsighted since a lot of "console" players are really serious about their roleplaying but for whatever reason prefer to play on a console.
And people say that the pc-folks gets shafted in this deal

Im a console player, and i rolepay, just as you said. I cant afford a gaming-pc. Do Bethesda consider all console owners idiots?
Actually, they could include a whole bunch of toggles in the next DLC/expansion. One can dream right?
