I still play it
Guilty Gear Xrd -SIGN- is still going strong, and Arc System Works has a new patch in the works, primarily to improve the netcode. Additionally, cross-platform play will be stabilized, and a few other bugs will be fixed including trophy problems, DLC system voice issues, and a few typos.
Beginner lobbies have been increased, and the system will now kick you if you’ve been idle for more than 15 minutes — thankfully, a voice will now come on when it’s your turn to notify you. Arc is teasing another patch later this year that will bring balance changes and more online improvements.
