Then I feel like that: "I got that far, losed so many health potions, took my precious time just to get this?! This dungeon looked so epic but all that is hidden in it is a steel sword?"
The same with scaled enemies, it's so annoying that there is nothing to stop me from going to a certain place. Maybe I want to have some cool looking places with cool loot to be blocked for me by strong enemies unless I'm powerful enough and have good tactics to get there?
There are no different parts of map with unique enemies, because you can get the same enemy wherever you are, they've got just different colors and are called for example "ice wolves" or something like that.
What do you think?
