There is a difficulty setting for just this reason... you think it's too easy? crank it up a notch or two.
It can't go above master which is what I'v been playing on.
Even without enchanting/blacksmithing, archery is still insane, especially if you're a stealth archer like I am. I have 200% stealth from my armor and 160% stronger archery from +archery gear so it's still really powerful. I can easily sit at the back of a room and pick off 8 guys in a row without having a single one spot me.
There'll be mods eventually though that'll work on difficulty and balancing so it's not to big of a deal I guess.
Enchanting,Smithing,1 Handed,and Block is most overpowred specs.
Others are fine
Oh yeah? So taking damage and clearing slower is more overpowered than 1 shotting everything while never taking damage?
