So, as the title says, what are the things in Fantasy settings you don't like? I will list mine.
1 - The extremely beautiful, long lived, sage elves. Don't get me wrong, I like this type of elves but they are just "out dated". I liked what The Witcher's writer did. They once were like this, but now they are just a shadow of it. Oh and yes, I love TES elves because they are just the opposite of this type of elves, but I am not a lore sage, so...
2 - The lack of a deep story and cultural aspects of its world. One thing that buggers me a lot.
3 - MAGIC EVERYWHERE! It may seem a little dumb "hey you want to reed/play/watch fantasy stuff but don't want to see a lot of magic?" but truth is, I like when magic is there but not everywhere.
4 - Unrealistic weapons and armor design. I just can't stand that 1,8 meters sword with a edge of 10cm. Or that over sized armor.
these are the things that really buggers me in a Fantasy Setting.
