The real reason is he loved doing all the level cap endgame stuff but isn't a fan of story based games which is a massive portion of FF14. Pretty sure he didn't mind the FF14 community and still praises the FF14 GM team for how quickly they dealt with issues related to the community being complete jerks to him when he was streaming. Obviously it was because he is a streamer that he got such quick resolution to issues since there were hundreds of thousands of people watching it and it was pretty much right there for the GMs to follow and see who is being a jerk.
