Well preface this by saying there's nothing wrong with needing a breather away from the game a bit if it's getting stale.
I love the story. I love tradeskilling. I've been finishing animas I hadn't in the past because I like getting shiny toys. I still find satisfaction in checking off my weekly tomes and getting my new armor. I like customizing glams for each of my classes, so the new plates coming are a Twelvesend. I love the Panda raids (except P2, that one can go rot) and I'm excited to wipe repeatedly on launch day with Myths. I like leveling new classes and seeing how they play differently than my WHM main.
What have you enjoyed in the game so far? That might help us get you excited about certain things or maybe someone's mentioned something that caught your interest that's new that you can try out.
