expert = normal mode imo. anything less and the game is too easy, Even on adept.
Not remotely. I've played extensively on Master and Expert with a lvl 61 with a bow and swords. Both difficulties are simply ridiculous. They are almost exactly like turning up the difficulty in Oblivion. Unrealistic/implausible enemies, with crazy high power and incalculable resistances to damage of all kinds. Tedious, boring, and frustrating, as well as demeaning to the point of "getting stronger" for the PC. Don't even get me started on the ridiculousness of NPC mages(which are screwed up on any difficulty), but playing as a mage is pointless when these high "difficulty" levels are used.
I have a real problem with a shirtless guy wearing furs, trained to 100 on all skills, who can survive the absurd amount of damage I'm supposed to be doing with the BEST gear in the game(and I don't even need to enchant any gear to kill anything on master). Master makes enemies do 2.0x damage, and you do .50x damage to them....which is just stupid. In ANY game.
Bethesda truly screwed up when they made the difficulty levels for this game, just like Oblivion.
Let me stop before I write a whole thread on this topic, as it's the number one game design flaw with Skyrim that I will never understand.
OT: I play all my characters on Adept now, including my pure mage, because it at least makes sense (most of the time). Am I coping with bad game mechanics to make a pure mage viable? Yes. Should I have to? No.
