@biggfelix Why not? Is it because it's something that YOU would find boring? I mean we don't need pets either but those are probably coming in 2019. What makes fishing, gambling, a social HUB, etc. fun is that they're all mini games. From a developer standpoint they keep players entertained when they want to take a break from the day to day game play of your game. It gives players something to do while they continue to enjoy in the world you've created. It also leads to social interactions, and this game is fueled by social interactions, which can lead to other adventures and stories. Not to mention fishing would be an excellent way for other players to share the stories they've gathered with one another.
Fishing will more than likely be apart of this game at some point. The developers have stated that they're interested in doing it and a very large part of the player base has supported the idea as well.
