It's interesting that people expect developers to release balance fixes for everything. I've yet to play a single-player game with a massive balance fix. Even DE:HR with its horrible boss battles was never fixed - and this game needed it even more desperately than Skyrim.
Like asker said, spamming iron daggers doesn't work anymore. Instead, you can spam jewellery and all things dwarven. This is the only change.
I recommend you buy the PC version and install balancing mods.
I was silly enough to buy the 360 version last time.
I don't think my laptop can run Skyrim.
I have yet to play a singleplayer game where summoned MINIONS deal more spell damage than my own spells.
That was the truth of it when I left the game:
A conjurer / archer dealt more bow damage and had fire atronaches that dealt more fire damage than a destruction mage.
...
So after playing a conjurer / archer, I didn't feel any need what so ever to continue my destruction mage who was a gimp compared to my conjurer.
I did enjoy the game immensely, and consider the game great -- but the balance!
It takes 10 hours in real life / 10 days ingame for a level 1 character to make stronger artifacts than the gods are capable of making.
Why?
A destruction mage cannot compete with archers nor conjurers for ranged damage.
Why?
