Minor manga spoilers:
So since I wrote the comment, I actually started the manga (Which honestly isn’t that good, it’s just walls upon walls of text) and Kurapika becomes extremely important if not the main character after the anime ends. Generally I’d honestly agree with the whole ending not making a whole lot of sense, esp. considering how everything after the anime just becomes a huge mess and feels completely unrelated to the HunterXHunter story we had so far.
