people these days on Wattpad cannot come up with that good of descriptions (even me) anymore. it's sad *cries*
1) the spoilers
some descriptions give away the whole story. nobody wants to read a story if the description already tells you what the ending is like!
example: Bob was not normal. He is evil. So when he meets another guy just like him and they team up and kill everyone, what will happen next? They kill each other of course. ASDFGHJKL
2) the copiers
example: 1D AU in which a woman meets one direction. WHY IS IT THAT IN EVERY 1D STORY THE DESCRIPTION STARTS WITH IN WHICH ;-;
please let us be creative again
