I hate timeskips. They are the worst thing the Universe can provide. You can timeskip if you fill the space with a small summary of what happened, it's okay. Just don't drop me into another world with a turn of a page. Reach the conclusion, finish everything that's been going on, wrap up the story. Then, sure. A nice epilogue like 'what happens in 5-20 years with the heroes of the story' is fine. I like that. Why do they have the need to do that in the middle? WHY? I hate timeskips. The are the single bad thing the Universe can provide.
