Wow. Thank you for posting this. How incredibly unfortunate.
Exo was always one of my favorite people to play FF with and he was an integral part of the community for a really long time (he was one of the handful of people there on day 1 of #ff.pickup). I'll always remember the hours and hours of 2v2s I played with/against him in those early days.
Here's to hoping he recovers.
