Hey there,
It's unfortunate to hear that you haven't been enjoying the game as of late. When referring to the Core Combat Update, are there any specific aspects of the CCU you dislike, or are you not a fan of it as a whole? I would really love for you to provide a bit details if you're willing to share. If you still choose to leave the game, I want to wish you well in your future gaming endeavors. Hopefully something will be introduced to the game that'll entice you to return one day.
