People are complaining already? That was fast.
I happen to enjoy the game, mostly because I don't break immersion just by having a marker on the compass.
I mean, it's impossible for Adventurer to have a compass, right? Or mark something on his map?
And while the dungeons backtracking is sort of strange, it's a hell of a lot better than getting stuck in a hole and having to reload. If we were going for 100% realism, there would have to be a entire minigame based around shoving a full suit of Elven armor into your backpack. Not to mention your hundreds of dwarven arrows that should be impossible to carry. Oh, and swimming in heavy armor? They should take that out, because it's totes unrealistic. Most of the light armor too.
As for trainers, who gets more skilled in armor within an hour/week? Crazy. They need to go. For that matter, the HP system should be replaced by a DF like system that requires hours of pouring over your old anatomy texts to find the most optimal place to stab the next bandit.
Also elves and dwarves and dragons never existed and shouldn't be in the game. Why are there so many caves? What about the polytheism that shouldn't be so prevalent during that time period?

Tl;Dr calm down it's a game. It's not going to be perfect so don't sweat the small stuff and look at the game as a whole.
